Astudent claims that water's polarity is the reason it has a high specific heat. what method could the student use to test his claim? perform research to see if other polar molecules have high specific heat. measure how much energy it takes to increase the temperature of water by one degree. mix water with an acid and test the new specific heat. determine how dissolving salt in water affects the specific heat.

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer. the ice dissolves oxygen from the air, forming a denser crystalline matrix. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.
