A cylinder with a piston holds 4.50 moles of a monatomic gas. The gas in the cylinder absorbs 935 J of energy due to the higher temperature of the environment. At the same time, the cylinder expands to a larger volume, doing 152 J of work on the environment. (a) What is the change in internal energy of the gas in the cylinder (in J)? (b) What is the change in temperature of the gas (in K)?

An ideal gas with γ = 1.40 occupies 8.26 L at 335 K and 79.2 kPa pressure. It's compressed adiabatically to one-third of its original volume, then cooled at constant volume back to 335 K. Finally, it's allowed to expand isothermally to its original volume. How much work is done on the gas?

A sample of N molecules of ideal gas expands with no energy transferred into or out of the gas by heating. The pressure and volume of the gas are measured as it expands, and a graph of pressure as a function of volume is used to calculate the work done by the gas. Which of the following indicates a quantity for the gas that can be determined using the calculated work and justifies why it can be determined? Select two answers. The magnitude of the change in internal energy of the gas can be determined. If no energy is transferred by heating, the magnitude A of the change in internal energy equals the magnitude of the work done by the gas. The change in potential energy of the gas can be determined. The internal energy of the gas equals its potential energy plus its kinetic energy, and the magnitude of the change in kinetic energy of the gas equals the work done by the gas. The magnitude of the change in the average kinetic energy of a molecule of the gas can be determined. The magnitude…
