b Boyle's law states that at constant temperature, for a fixed mass of a gas, $PV$= constant
But if the temperature remains constant, it will be called as an isothermal change.
So $B$ is correct.

For a gas, the difference between the two specific heats is $4150\, J\, kg^{-1}\, K^{-1}$ and the ratio of the two specific heats is $1.4$. What is the specific heat of the gas at constant volume in units of $J\, kg^{-1}\, K^{-1}$ ?
Two non-reactive monoatomic ideal gases have their atomic masses in the ratio $2: 3$. The ratio of their partial pressures, when enclosed in a vessel kept at a constant temperature, is $4: 3$. The ratio of their densities is:
The molar specific heat at constant pressure of an ideal gas is $(7/2)R.$ The ratio of specific heat at constant pressure to that at constant volume is
