A cylinder contains 1.2 moles of ideal gas, initially at a temperature of 116°C. The cylinder is provided with a frictionless piston, which maintains a constant pressure of 6.4 x 10⁵ Pa on the gas. The gas is cooled until its temperature has decreased to 27°C For the gas
and the ideal gas constant
(a) Find the work done by (or on) the gas during this process. Is the work done by or on the gas?
(b) What is the change in the internal (thermal) energy of the gas during this process?
(c) How much heat is transferred to (or from) the gas during this process? Does this heat flow into or out of the gas?
