How to cool down a can of drink in 2 minutes. A simple science trick to give you aspeedy ice cold beverage which won't get diluted like it would if you were to put icecubes in your drink. Perfect for cooling beer and soda cans in an emergency, andyou can even use it for chilling wine bottles.

Take your bowl fill it with water until its roughly one third full. Then take some ice

cubes from the freezer and tip them into the bowl. I used two trays of ice cubes.

Next add a couple of table spoons of salt into the ice water and stir it in. As the salt

dissolves into the water, it will actually disassociate into its constituent, sodium andchloride ions. Water molecules are polar, and each molecule has a partiallypositive and a partially negative charged end. The negative end attracts the positivesodium ion, and the positive end attracts the negative end. This process (known assolvation) requires energy which is obtained by reducing the thermal energy of thewater, hence reducing the temperature of the salt ice-water mix. The ice will notonly melt, but actually get colder!

Once you've stirred in the salt, carefully place your drink into the solution andsubmerge it.

As the salt ice-water solution is so much colder then the room temperature drink,the heat energy in the can will be drawn out and the temperature of the drink insidethe can will rapidly reduce.

Second law of thermodynamics states: Two substances with different temperatures reach thermal equilibrium over time.

After a minute give it all a good stir with a spoon and after 2 minutes its ready totake out. The temperature of your drink will have reduced significantly, and you cannow enjoy a nice cold ice cold drink!

Step 5: Measure The Change

If you like you can monitor the temperature change by checking the temperature of a room temperature can, and comparing it to the temperature of a can after itsbeen cooled in the solution. I left the can in the solution for 2 minutes and found thetemperature fell from 75°F (24°C) to 41°F (5°C) which is a reduction intemperature of 34°F or 19°C.

This science is not only a fun and practical way to quickly cool down your drink,but it can also be used for making home made ice-cream.

What would have been neat is i f you did the same thing in another bowl but didnot use the salt to find out how much the salt helped cool the drink.

But still really cool.

gthompson20 (/member/gthompson20/) Zendo_Xarth

That is absolute rubbish about the sodium and chlorine dissociating. Theydo no such thing the salt i s just dissolved in the water turning it into saltwater which has a freezing point of 0 deg F when the temp of the ice canbe as high as 32 deg F

Since i t has now been turned into salt water the latent heat of the fusion of the ice has to be replaced and it i s absorbed from the surrounds. If my

memory serves me right, from high school physics, this is how 0 deg Fwas originally defined

The same mechanism can be used to actually freeze pure water if isolated from the salt.

it's pretty well known that sodium chloride dissociates when it's dissolvedin water.

gthompson20 (/member/gthompson20/) discostu956

Well it looks like my chemistry teacher was tellyme a load of BS. It doesn't change the fact that 50

years ago this method was used in toy ice creammakers to obtain sub zero C temperatures, it i s

just rehashing what most people already know

Second law of thermodynamics states: Two substances with different temperatures reach thermal equili brium over time...

I'm afraid this is zeroth law of thermodynamics which says:

if two bodies are in thermal equilibrium with a third body, they are also in thermalequilibrium with each other,or two bodies are in thermal equilibrium if both have the same temperature reading even if they are not in contact

.

.

The first law of thermodynamics is simply an expression of the conservation of energy principle,and it asserts that energy is a thermodynamic property.

Second law of thermodynamics states:

It is impossible for any device that operates on a cycle to receive heat from asingle reservoir and produce a net amount of work(Kelvin–Planck statement)

or

It is impossible to construct a device that operates in a cycle and producesno effect other than the transfer of heat from a lower-temperature body to ahigher-temperature body(Clausius statement)

I always just put it in the microwave and set the timer to a negative number.

harmonious1 (/member/harmonious1/)

Well that's how we USED to make ice cream.

curbdiver (/member/curbdiver/)

Spinning the container sideways in the bowl will cool the contents with out salt.Salt should cool it faster.I bought a machine at a yard sale that had a tray to hold the ice and a motor witha suction cup on the shaft to attach to the bottom of the can.It would cool the contents without shaking it up by cooling the outside of the canas it sun around

Bowtie41 (/member/Bowtie41/)

I've heard of this before but never tried it.Does it make the ice all melt down super fast?I was thinking of trying this with our coolers of drinks at family get-togethers.Anyone know how much salt would be needed for say,a cooler with
