Log P vs log V curve is plotted for an ideal gas, which is true for the gas ?

Options

A. Monoatomic & undergoing adiabitc chagre
B. Monatomic & undergoing an isothermal change
C. Diamtomic & undergoing an adiabitc charge
D. Triatomic & undergoing an isothermal change

Answer

C

Explanation

Equation of processe
`(log P-2.38)/(log V-1.10)=(2.10-2.38)/(1.30- 1.10)=(-0.28)/(0.20)=(-7)/(5)`
`rArr(log P-2.38)xx5= -7 (log V-1.1)`
`rArr5 log P + 7 log V= 19.60`
`rArrlog P^(5) + log V^(7) = 19.60 `
`P_(5)V_(7)` = antilog (19.60) = constant
or `PV^(1.4)` = constant
`therefore gamma = 1.4 - "diatomic & adiabatic"`
