Physical Properties of Matter
PHYSICAL PROPERTIES
These are qualities of a matter that can be detected using our five senses or through a measuring device without changing its composition.
Examples of Physical Properties
1.E N G S T R THThe _______ of a material refers to its ability to support a heavy load without breaking or tearing.
Examples of Physical Properties
1.STRENGTHThe strength of a material refers to its ability to support a heavy load without breaking or tearing.
Example: steel vs paper
Examples of Physical Properties
2. S E A N S D R H
