Which of these statements are true? -The internal energy of any gas depends only the temperature of the system. - The internal energy of a gas always increases with temperature -The heat capacity of a monoatomic ideal gas is always smaller than the heat capacity of a polyatomic ideal gas. - q = 0 for any process that does not result in a change in temperature.

Which of the following statements about pressure-volume work is true? The reversible process provides the maximum amount of work. Work done at constant-pressure is zero. When work is done on the system in an adiabatic process there is a decrease in the internal energy of the system. Changes in pressure-volume work must always be offset by changes in the heat of the system. A free expansion takes place against a constant external pressure of 1 bar.

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)...

Learning Goal Internal Energy of an ideal gas The internal energy of a system is the energy stored in the system. In an ideal gas, the internal energy includes the kinetic energies (translational and rotational) of all the molecules, and other energies due to the interactions among the molecules. The internal energy is proportional to the Absolute Temperature T and the number of moles n (or the number of molecules N). n monatomic ideal gases, the interactions among the molecules...

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...
