A sample of ideal gas havingfdegrees of freedom and containingnmoles are confined to a cylinder with a frictionless piston. The pressure in and out of the cylinder are equal. However, the temperature ofthe gas inside the cylinder is To while the outside is a heat reservoir at temperature TH, assumed greater than To. As the gas inside the cylinder absorbs heat from the outside it begins an isobaric expansionuntil its temperature reaches TH.

Required:
Determine an expression for the heat transferred to the gas from the heat reservoir in terms of f, n, T., To, and the gas constant R.
