An air pump has a cylinder 0.300 m long with a movable piston. The pump is used to compress air from the atmosphere (at absolute pressure 1.01 ∗ 105 Pa) into a very large tank at 3.00 ∗ 105 Pa gauge pressure. (For air, CV = 20.8 J/mol * K.) (a) The piston begins the compression stroke at the open end of the cylinder. How far down the length of the cylinder has the piston moved when air first begins to flow from the cylinder into the tank? Assume that the compression is adiabatic. (b) If the air is taken into the pump at 30.0 C, what is the temperatu

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