A sample of an ideal gas has pressure p_(0) , volume V_(0) and tempreture T_(0) . It is isothermally expanded to twice its oringinal volume.it is then compressed at constant pressure to have the original volume V_(0) . Finally, the gas is heated at constant volume to get the original tempreture.(a) show the process in a V-T diagram (b) calculate the heat absorbed in the process.
