An ideal gas has pressure p_(0), volumn V_(0) and temperature T_(0). It is taken an isochoric process till its pressure is doubled. It is now isothermally expanded to get the original pressure. Finally , the gas is isobarically compressed to its original volume V_(0). (a) Show the process on a p-V diagram. (b) What is the tempertaure in the isothermal part of the process? (c) What is the volumn at the end of the isothermal part of the process?

Solution :

The process is shown in a `p-V` diagram in figure. The process starts from `A` and goes through `ABCD` <br> <img src="https://d10lpgp6xz60nq.cloudfront.net/physics_imagesHCV_VOL2_C24_S01_009_S01.png" width="80%">` <br> (b) Applying `pV = nRT at A and B` <br> `p_(0)V_(0)=nRT_(0)` <br> and `(2p_(0)V_(0)=n RT_(B)` <br> thus, `T_(B) = 2 T_(0)` <br> Thus is the temperatrue in the isothermal parts BC, <br> (c) As the process `BC` is isothermal `T_(C) = T_(B) = 2T_(0)` applying `pV = nRT` at A and C <br> `p_(0)V_(0)=nRT_(0)` <br> and `p_(0)V_(c)=nRT(2T_(0))` <br> or, `V_(c)=2V_(0)`.

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.

For an ideal gas with initial pressure and volume `p_(i) and V_(i)` respectively, a reversible isothermal expansion happens, when its volume becomes `V_(0)`. Then it is compressed to its original volume `V_(i)` by a reversible adiabatic process. If the final pressure is `p_(f)`, then which of the following statement is true?
