19.20 During an isothermal compression of an ideal gas, 335J of heat must be removed from the gas to maintain constant temperature. How much work is done by the gas during the process? Prepared by Vince Zaccone For Campus Learning Assistance Services at UCSB

Prepared by Vince Zaccone For Campus Learning Assistance Services at UCSB Heat Q flows into a monatomic ideal gas, and the volume increases wile the pressure is kept constant. What fraction of the heat energy is used to do the expansion work of the gas?

19.26 When a quantity of monatomic ideal gas expands at a constant pressure of 4x10 4 Pa, the volume of the gas increases from 2x10 -3 m 3 to 8x10 -3 m 3. What is the change in the internal energy of the gas? Prepared by Vince Zaccone For Campus Learning Assistance Services at UCSB

19.28 Three moles of an ideal monatomic gas expands at a constant pressure of 2.5 atm; the volume of the gas changes from 3.2x10 -2 m 3 to 4.5x10 -2 m 3. (a)Calculate the initial and final temperatures of the gas. (b)Calculate the amount of work the gas does in expanding. (c)Calculate the amount of heat added to the gas. (d)Calculate the change in internal energy of the gas. Prepared by Vince Zaccone For Campus Learning Assistance Services at UCSB
