A 5 mole sample of liquid acetone is converted to a gas at 75. 0°C. If 628 J are required to raise the temperature of the liquid to the boiling point, 15. 600 kj are required to evaporate the liquid, and 712 J are required to raise the final temperature to 75. 0°C, what is the total energy required for the conversion?

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.
