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.
I am not sure how to approach solving this problem. All questions are part of Part 1. Any help would be greatly appreciated!

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...
D. An ideal gas is contained in a cylinder that is fixed in Ideal gas place. The cylinder is closed by a piston, as shown in the diagram at right. There is no friction between the piston and the cylinder walls. 1. Describe the direction of the force that the piston exerts on the gas. Does your answer depend on whether the piston is moving? 2. How could the piston move so that the work it does on the gas...
One mole of an ideal gas is confined to a container with a movable piston. The questions below refer to the processes shown on the PV diagram at right. Process I is a change from state Xto state Y at constant pressure. Process Il is a change from state W to state Z at a different constant pressure Rank the temperatures of states W, X, Y, and Z. If any temperatures are equal, state that explicitly. Explain. a. b. x...
4. A piston-cylinder device contains 0.8 kg and 1 m' of an ideal gas whose molar mass is 4 g/mol. The wall of the cylinder is thermally conductive with the surrounding, which is at the room temperature 25 °C. Now th e gas is compressed isothermally, and 150 kJ of heat is conducted out to the surroundings during the whole process. Deternine the firal volu me.
A cylindrical canister fitted with a piston at one end contains an ideal gas and floats at the surface of a freshwater lake, where the temperature is 300 K. The gas pressure inside the canister is just enough to balance atmospheric pressure, and so the piston does not slide downward. Initially the canister volume is 3.24 L . The canister is lowered into the lake until it is 12.0 m below the surface, where the temperature is 280 K. Ignore...
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...
A container holds a sample of ideal gas in thermal equilibrium, as 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. Refer to the pV diagram presented to answer the questions below. (Figure 2) In each case, the piston...
105Pa, initial temperature T-300K, and an initial 1. An ideal gas with initial pressure 2 volume V - 1m3 expands isothermally to a final volume of 2m3. Then, the gas returns to its initial state, first by constant pressure (isobaric) contraction, and then by a change at constant volume (isochoric) a) Draw a PV diagram of this process. What's the total change in thermal energy of the entire process? b) What's the work done by the environment on the gas?...
