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 reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.
the ice dissolves oxygen from the air, forming a denser crystalline matrix.
the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.
the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.

Name three different units of energy used to measure heat and describe what type of situations each is usually used.

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat
