Consider a two-step process. Heat is allowed to flow out of an ideal gas at constant
volume so that its pressure drops from 3.3 atm to 1.8 atm. Then the gas expands at
constant pressure, from a volume of 4.5 L to 9.7 L, where the temperature reaches
its original temperature.
a) Sketch the PV diagram for this process.
b)calculate the work done by the gas in the process
c) Calculate the changes in the internal energy of the gas in the process
d) Calculate the heat flow into or out of the gas ​
