Problem 4

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 m312.0 \textrm{ m}^3 to 16.2 m316.2 \textrm{ m}^3. Calculate

  1. the work done by the gas and
  2. the change in internal energy of the gas.
  1. 4.25×105 J4.25 \times 10^5 \textrm{ J}
  2. 6.38×105 J6.38 \times 10^5 \textrm{ J}
