Refer above figure and answer the following questions. (i) What is the work done in process AB ? (ii) What is the change in internal energy and heat released in process BC ? |
|
Answer» (i) In this case, the change in the internal energy is zero, as the temperature of the gas remains constant. Hence, the work done, W = heat absorbed, QH . (ii) In this case, the change in the internal energy, ∆ U = nCV (TC – TH), where n = number of moles of the gas used in the Stirling engine and CV = molar specific heat of the gas. As W = 0 at constant volume, heat released’= ∆ U. |
