Question:
A gas is enclosed in a cylinder fitted with a light frictionless piston and maintained at atmospheric pressure. When 254 kcal of heat is added to the gas, the volume is observed to increase slowly from $12.0 \textrm{ m}^3$ to $16.2 \textrm{ m}^3$. Calculate
- the work done by the gas and
- the change in internal energy of the gas.
