In the pV diagram shown in the figure (Figure 1), 80.0 J of work was done by 0.0610 mole of ideal gas during an adiabatic process.
a) How much heat entered or left this gas from a to b? Express your answer in joules.
b) By how many joules did the internal energy of the gas change? Express your answer in joules.

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?
