Question

Consider the process shown on the PV diagram to the right. In this process, two moles of a monatomic ideal gas perform a complete cycle from the initial state i to state a, then to state b, and then back to state i. You will be concerned only with the step from a to b.

a) Calculate the change in the temperature of the gas from a to b. (Note that the pressure axis is multiplied by 10^5 Pa and the volume axis by 10^-3 m^3 .)

b) Calculate the change in internal energy of the gas from a to b

c) Calculate the work done on the gas during the step from a to b and then answer the following question: Does energy enter or leave the gas in the form of work during this step? 

d) Calculate the heat transferred to the gas during the step from a to b and then answer the following question: Was the gas at a higher or lower temperature than the environment during this step?
