Assume that helium behaves as an ideal monatomic gas. If 76 moles of helium undergo a temperature increase of 245 K at constant pressure, how much energy (in J) has been transferred to the helium as heat? Round your answer to the nearest whole number.
A cylinder with a movable piston contains 17.5 moles of a monatomic ideal gas at a pressure of 1.66 × 105 Pa. The gas is initially at a temperature of 300 K. An electric heater adds 46600 J of energy into the gas while the piston moves in such a way that the pressure remains constant. It may help you to recall that CPCP = 20.79 J/K/mole for a monatomic ideal gas, and that the number of gas molecules is...
Twenty moles of a monatomic ideal gas (? = 5/3) undergo an adiabatic process. The initial pressure is 400 kPa and the initial temperature is 450 K. The final temperature of the gas is 320 K. In the situation above, the change in the internal energy of the gas, in kJ, is closest to:

A cylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32 × 105 Pa. The gas is initially at a temperature of 300 K. An electric heater adds 43200 J of energy into the gas while the piston moves in such a way that the pressure remains constant.

A piston contains 580 moles of an ideal monatomic gas that initally has a pressure of 1.06 x 105 Pa and a volume of 1.3 m3. The piston is connected to a hot and cold reservoir and the gas goes through the following quasi-static cycle accepting energy from the hot reservoir and exhausting energy into the cold reservoir. The pressure of the gas is increased to 4.06 x 105 Pa while maintaining a constant volume. The volume of the gas...
102) 2.37 moles of an ideal monatomic gas initially at 255 K undergoes this cycle: It is (1) heated at constant pressure to 655 K, (2) then allowed to cool at constant volume until its temperature returns to its initial value, (3) then compressed isothermally to its initial state. Find: a. the net energy transferred as heat to the gas (excluding the energy transferred as heat out of the gas). b. the net work done by the gas for the...
A tank with a constant volume of 5.89 m3 contains 15 moles of a monatomic ideal gas. The gas is initially at a temperature of 300 K. An electric heater is used to transfer 56500 J of energy into the gas. It may help you to recall that CVCV = 12.47 J/K/mole for a monatomic ideal gas, and that the number of gas molecules is equal to Avagadros number (6.022 × 1023) times the number of moles of the gas....
Suppose that 292 moles of a monatomic ideal gas is initially contained in a piston with a volume of 1.34 m3 at a temperature of 588 K. The piston is connected to a hot reservoir with a temperature of 1385 K and a cold reservoir with a temperature of 588 K. The gas undergoes a quasi-static Stirling cycle with the following steps: The temperature of the gas is increased to 1385 K while maintaining a constant volume. The volume of...
A sample of helium behaves as an ideal gas as it is heated at constant pressure from 273 K to 402 K. If 25.0 J of work is done by the gas during this process, what is the mass of helium present? mg
