Two ***** of a certain ideal gas at a temperature To = 300 K were cooled isochorically so that the gas pressure reduced n = 2.0 times.

Question

Two ***** of a certain ideal gas at a temperature T0 = 300 K were cooled isochorically so that the gas pressure reduced n = 2.0 times. Then, as a result of the isobaric process, the gas expanded till its temperature got back to the initial value. Find the total amount of heat absorbed by the gas in this process

Answer 1

Let v = 2 ***** of the first phase, under isochoric process, A1 = 0, therefore from gas law if pressure is reduced n time so that temperature i.e. new temperature becomes T0 /n.

Now from first law of thermodynamics
