Best ResponseYou've already chosen the best response.0A piston contains 100 moles of an ideal monatomic gas that initally has a pressure of 2.19 × 105 Pa and a volume of 2.7 m3. The piston is connected to a hot and cold reservoir and the gas goes through the following quasistatic cycle accepting energy from the hot reservoir and exhausting energy into the cold reservoir. The pressure of the gas is increased to 5.19 × 105 Pa while maintaining a constant volume. The volume of the gas is increased to 9.7 m3 while maintaining a constant pressure. The pressure of the gas is decreased to 2.19 × 105 Pa while maintaining a constant volume. The volume of the gas is decreased to 2.7 m3 while maintaining a constant pressure. It may help you to recall that CV = 12.47 J/K/mole and CP = 20.79 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.

Best ResponseYou've already chosen the best response.0So i know we have to use PV=nRT to solve for initial temp T = PV/nR i have done this and the T initial comes out as 711.14 K Now i have to calculate for delta T when the pressure increases (step 1, constant V) and also delta T when the volume increases (step 2, constant P)
