Degrees of Adjectives
Day1
Degrees of Adjectives
An adjective is a word which modifies (tells us more about) a noun or a pronoun.
Examples: hot tea, old man, beautiful girl, white shirt, intelligent student, interesting
story, handsome boy, huge room.
In the above examples, „hot, old, beautiful, white, intelligent‟ are adjectives because
they modify (give more information about) the attached nouns.
Every adjective has its three degrees.
1. Positive Adjective
2. Comparative Adjective
3. Superlative Adjective
These three degrees of an adjective express the intensity of adjective in increasing
order e.g. big – bigger – biggest, good – better – best.
Day2
Examples:
Positive Comparative Superlative
Happy Happier Happiest
Heavy Heavier Heaviest
Large Larger Largest
Short Shorter Shortest
Lucky Luckier Luckiest
Day3
Old Older Oldest
Many More Most
Little Less Least
Bad Worse Worst
Horrible More horrible Most horrible
Attractive More Attractive Most Attractive
Beautiful More beautiful Most beautiful
Day4
Use of Comparative Adjectives A comparative adjective is used to show a characteristic or a property of one thing
(noun or pronoun) in a comparison to another thing (only one thing).
It makes comparison between two things (not more than two).
Words like “than” & “to” are used after a comparative adjective in a sentence to
show comparison of the two things.
Examples:
1. A bus is bigger than a car.
2. She is cleverer than him.
3. A car is heavier than a bicycle.
4. You are taller than me.
5. He is more handsome than his brother.
6. Your voice is louder than her voice.
Day5
Use of Superlative Adjective A superlative adjective is used to show a characteristic or a property of one thing
(noun or pronoun) in a comparison to many other things (many things, more than one).
It makes comparison of one thing to many other things.
A superlative degree expresses highest intensity (i.e. quality or quantity) of a
thing in a comparison to other many things (not one but more than one).
A superlative adjective states that a thing is surpassing all the other things in
terms of property, characteristic or quantity.
Example:
John is the tallest boy of his class.
It means that John is surpassing all the boys of his class in tallness. No one other boy,
in the class, is taller than John. It makes the comparison of John and all the students of
his class.
Words like “of” and “in” are used after a superlative degree in the sentence. An
article “the” should be used before a superlative degree when modifying a particular
noun.
Some Examples:
1. Einstein was the most intelligent scientist in the world.
1. He is the richest man of the town.
2. He is the most brilliant boy of his class.
3. My room is the biggest of all room in my house.
4. Sara is the most talkative girl in his family.
5. A train is the fastest vehicle.
6. 6. Rive Nile is the deepest river in the world.

Lesson- 4 (Heat flow and temperature)
GENERAL INSTRUCTIONS:-
1. Please download e-book class- 7 science from internet.
2. Read the chapter thoroughly before doing the exercise questions.
3. This assignment is based on chapter-4 “(Heat flow and temperature)”.
4. Record all the exercise question answer in any register [ name it science].
DAY 1-3
A reliable measure of the hotness of an object is its temperature. Temperature is
measured by a device called thermometer. The thermometer that measures our body
temperature is called a clinical thermometer. A clinical thermometer consists of a
long, narrow, uniform glass tube. It has a bulb at one end. This bulb contains mercury.
Outside the bulb, a small shining thread of mercury can be seen. The scale we use is
the celsius scale, indicated by °C. A clinical thermometer reads temperature from 35°C
to 42°C.
Precautions to be observed while reading a clinical thermometer :-
# Thermometer should be washed before and after use, preferably with an
antiseptic solution.
# Ensure that before use the mercury level is below 35°C.
# Read the thermometer keeping the level of mercury along the line of sight.
# Handle the thermometer with care. If it hits against some hard object, it can break.
# Don‟t hold the thermometer by the bulb while reading it.
The normal temperature of human body is 37°C. The clinical thermometer is designed
to measure the temperature of human body only. The temperature of human body
normally does not go below 35Oc or above 42oC. That is the reason that this
thermometer has the range 35oC to 42oC. Do not use a clinical thermometer for
measuring the temperature of any object other than the human body. Also avoid
keeping the thermometer in the sun or near a flame. It may break.
LABORATORY THERMOMETER:
The range of a laboratory thermometer is generally from –10°C to 110°C. addition to
the precautions needed while reading a clinical thermometer, the laboratory
thermometer
# should be kept upright not tilted.
# bulb should be surrounded from all sides by the substance of which the temperature
is to be measured. The bulb should not touch the surface of the container.
In laboratory thermometer the temperature must be read while the thermometer is in
water/ in solution. but in clinical thermometer while taking your own temperature,
you have to take the thermometer out of your mouth to note the reading. The mercury
does not fall or rise in a clinical thermometer when taken out of the mouth. It is due to
presence of kink near the bulb. It prevents mercury level from falling on its own.
CAUTION
Do not use a clinical thermometer for measuring the temperature of any object other
than the human body. Also avoid keeping the thermometer in the sun or near a flame.
It may break.
NOTE : The maximum and minimum temperatures of the previous day, are measured
by a thermometer called the m a x i m u m - m i n i m u m thermometer.

DAY 4-6
TRANSFER OF HEAT
The heat flows from a hotter object to a colder object.
The process by which heat is transferred from the hot object to the cold object
without the actual movement of particles is known as conduction. In solids, generally,
the heat is transferred by the process of conduction.
The materials which allow heat to pass through them easily are conductors of heat.
For examples, aluminum, iron and copper.
The materials which do not allow heat to pass through them easily are poor
conductors of heat such as plastic and wood. Poor conductors are known as
insulators.
The water and air are poor conductors of heat.
When water is heated, the water near the flame gets hot. Hot water rises up. The cold
water from the sides moves down towards the source of heat. This water also gets hot
and rises and water from the sides moves down. This process continues till the whole
water gets heated. This mode of heat transfer is known as convection.
The air near the heat source gets hot and rises. The air from the sides comes in to take
its place. In this way the air gets heated.
SEA BREEZE AND LAND BREEZE
The people living in the coastal areas experience an interesting phenomenon. During
the day, the land gets heated faster than the water. The air over the land becomes
hotter and rises up. The cooler air from the sea rushes in towards the land to take its
place. The warm air from the land moves towards the sea to complete the cycle. The
air from the sea is called the sea breeze. At night it is exactly the reverse . The water
cools down more slowly than the land. So, the cool air from the land moves towards
the sea. This is called the land breeze.
When we come out in the sun, we feel warm. The heat from the sun cannot reach us by
conduction or convection as there is no medium such as air in most part of the Space
Between the earth and the sun. From the sun the heat comes to us by another process
known as radiation. The transfer of heat by radiation does not require any medium. It
can take place whether a medium is present or not. When we sit in front of a room
heater, we get heat by this process. Our body too, gives heat to the surroundings and
receives heat from it by radiation.
All hot bodies radiate heat. When this heat falls on some object, a part of it is
reflected, a part is absorbed and a part may be transmitted. The temperature of the
object increases due to the absorbed part of the heat.
In summer we prefer light-coloured clothes and in winter we usually wear dark-
coloured Clothes. Dark surfaces absorb more heat and, therefore, we feel comfortable
with dark coloured clothes in the winter. Light coloured clothes reflect most of the
heat that falls on them and, therefore, we feel more comfortable wearing them in the
summer.
In the winter, we use woollen clothes. Wool is a poor conductor of heat. Moreover,
there is air trapped in between the wool fibres. This air prevents the flow of heat from
our body to the cold surroundings. So, we feel warm. That‟s why two thin blankets
give more warmth than one thick blanket because a layer of air in between the
blankets.
Answer the following questions:--
Q.1. Give two examples each of conductors and insulators of heat.
Q.2. Fill in the blanks :
(a) No medium is required for transfer of heat by the process of __________.
(b) A cold steel spoon is dipped in a cup of hot milk. It transfers heat to its other end
by the process of ______________.
(c ) Clothes of ______________ colours absorb heat better than clothes of light
colours.
Q.3 Match the following :
(i) Land breeze blows during (a) summer
(ii) Sea breeze blows during (b) winter
(iii) Dark coloured clothes are preferred during (c) day
(iv) Light coloured clothes are preferred during (d) night
Q.4 Explain why wearing more layers of clothing during winter keeps us warmer than
wearing just one thick piece of clothing .?
Q.5. In places of hot climate it is advised that the outer walls of houses be painted
white. Explain.
Q.6 Define conduction and convection?
Q.7 Water and air are poor conductor of heat. Then how does the heat transfer take
place in these substances?
Q.8 Explain sea breeze and land breeze in coastal areas.
Q.9 Why are the handles of kitchen utensils made of wood or plastic?
Q.10. Define radiation.
