Question

During the process AB of an ideal gas

Moderate
Solution

P-T graph is a straight line passing through origin. There fore.
V = constant.

Work done on the gas = 0.

Further,

            ρ=mV1V

Volume of the gas is constant. Therefore, density of gas is also constant.

PV=nRTP=nRVT

i.e., slope of P-T line  n
