If an ideal gas is compressed

Options:(select one or more)

Answer:

A, D

Solution:

Isothermal: $P V =$ const $\Rightarrow κ = - \frac{1}{V} \frac{d V}{d P} = \frac{1}{P}$ (A true). Adiabatic: $P V^{γ} =$ const $\Rightarrow κ = \frac{1}{γ P}$ (D true, B false). At constant pressure during compression $T$ falls, so $v_{r m s} \propto T$ changes (C false).
