A sample of ideal gas at room temperature occupies a volume of
22.0 L at a pressure of 482 torr . If the pressure changes to 2410
torr , with no change in the temperature or moles of gas, what is
the new volume, V2?
1. A sample of ideal gas at room temperature occupies a volume

A sample of ideal gas is placed inside a balloon at room
temperature. The balloon is then put inside a freezer, where it
deflates without losing any of the gas inside it. The system is the
gas inside the balloon.
I - Represent this process with a PV diagram.
II - Was the change in internal energy of the system, positive,
negative, or zero? How do you know?
III - Was the work done by the atmosphere on the system...
A sample of an ideal gas at 1.00 atm and a volume of 1.46 L was
placed in a weighted balloon and dropped into the ocean. As the
sample descended, the water pressure compressed the balloon and
reduced its volume. When the pressure had increased to 10.0 atm,
what was the volume of the sample? Assume that the temperature was
held constant.
A sample of an ideal gas at 1.00 atm and a volume of 1.02 L was
placed in a weighted balloon and dropped into the ocean. As the
sample descended, the water pressure compressed the balloon and
reduced its volume. When the pressure had increased to 45.0 atm,
what was the volume of the sample? Assume that the temperature was
held constant.
A quantity of N molecules of an ideal gas initially occupies
volume V. The gas then expands to volume 2V. The number of
microscopic states of the gas increases in the expansion. Under
which of the following circumstances will this number increases the
most? ( i ) if the expansion is reversible and isothermal ( ii ) if
the expansion is reversible and adiabatic ( iii ) the number will
change by the same amount for both circumstances. Why ?
