An ideal gas is compressed reversibly and adiabatically from state a to state b. It is then heated reversibly at constant volume to state c. After expanding reversibly and adiabatically to state d such that T= Td, the gas is again reversibly heated at constant pressure to state e such that Te= Tc. Heat is then rejected reversibly from the gas at constant volume till it returns to state a. Express Ta in terms of Tb and Tc. If Tb = 555 K and Tc= 835 K, estimate Ta. Take γ= 1.4.
