The first part of the problem gave this info:
A sealed cylindrical pump contains one mole of an ideal gas. The piston fits tightly so that no gas escapes, but friction is negligible between the piston and the cylinder walls. The pump is thermally insulated from its surroundings. The piston is quickly pressed inward as indicated in the diagram. The pump is returned to its original state and then (without the insulation) placed in a very large container that is filled with an ice-water mixture. The system is allowed to come to thermal equilibrium at 0°C. The piston is then pressed inward very slowly.
I am not sure how to solve this question. Any help would be greatly appreciated!

The first law of thermodynamics D. The cylinder, with the piston still locked in place, is now immersed in a mixture of ice and water and allowed to come to thermal equilibrium with the mixture. The piston is then moved inward very slowly. in such a way that the gas is always in thermal equilibrium with the ice-water mixture. We will refer to this slow compression of the gas as process 3. 1. During process 3, do the following quantities...

1)Two rigid tanks of equal size and shape are filled with different gases. The tank on the left contains oxygen, and the tank on the right contains hydrogen. Assume both gases are ideal. The molar masses of oxygen and hydrogen are 32 and 2, respectively. Both containers are at the same temperature. A pressure gauge is pin oxygen hydrogen connected to each tank. Both gauges show a reading of 230 kPa. Is the number of oxygen molecules in the left...

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...

The first law of thermodynamics In thermal physics, we are often interested in the internal energy (E) of a system. The wo 41 internal energy of an ideal gas is proportional to the temperature and the number of moles of the gas. The internal energy can change when energy is exchanged with the system's environment (ie., objects that are outside the system of interest). The case above is one in which the internal energy of a gas changes due to...

4. The pressure-volume diagram below shows a special reversible cycle called the Carnot cycle A mole of an ideal gas starts off in state 1 in contact with a large thermal reservoir at temperature Th. The gas then undergoes an isothermal expansion from Vi to V2. Upon reaching state 2, the gas container is removed from contact with the thermal reservoir and covered with thermal insulation. Next the gas is allowed to expand adiabatically from V2to Vs. Because the expansion...

shown in the figure.
(Figure 1)
One end of the container is sealed with a piston whose head is
perfectly free to move, unless it is locked in place. The walls of
the container readily allow the transfer of energy via heat, unless
the piston is insulated from its surroundings.
