. An NIU student is playing around with a movable piston that
can compress the gas inside a cylindrical chamber. He decides to
compress the gas to 1/10th its initial volume to a pressure that is
30 times its initial pressure. If the initial volume was 0.055 m3
and the initial temperature of the gas was 25 °C, what will be the
final temperature of the gas?

24. Suppose that an ideal gas is inside a container with a movable piston. Which of the following statements is true? 1) Increasing the temperature of the system while keeping the volume constant causes the gas to perform work. 2) When work is done by the system on the surroundings while temperature is kept constant, the pressure of the gas increases. 3) If temperature is kept constant, then decreasing the pressure of the gas causes a increase in volume 4)...

The syringe shown at right contains nitrogen gas. The syringe
has a movable piston of mass M. At the bottom, the syringe is
closed by a valve, so that no gas may enter or leave the syringe.
(Neglect friction between the piston and the wall of the syringe.
Assume that nitrogen gas behaves like an ideal gas.) Initially the
syringe is in thermal equilibrium with an ice-water bath. The

Problem 4 (10 pts) A gas cylinder with a movable piston that is filled with argon gas experiences a drop in temperature from 56.0 C to 14.2 C and the piston's leaky seal loses 0.0048 mols of its initial 0.0132 mols before getting plugged. All of this transpires under a constant pressure of 1.024 atm. (a) The initial volume of the cylinder was 13.0 L. How many calories were transferred through work?

9. A container of ideal gas has a movable frictionless piston. This container is placed in a very large water bath and slowly compressed so that the temperature of the gas remains constant and equal to the temperature of the water. Which of the following statements about this gas are true for this process? The internal energy of the gas increases during the compression because work is done on the gas. Since the temperature of the gas remains constant, the...
