PhysicsMediummultiple choice

An ideal gas undergoes a process in which the number of collisions of the molecules per unit area of the wall in unit time is a constant. Then for this process

Options:(select one or more)

Answer:

C, D

Solution:

Collision rate per unit area $\propto \frac{N}{V} T \propto \frac{T}{V}$ . With $T \propto P V$ : rate $\propto \frac{P V}{V} = \frac{P}{V}$ . Constant rate $\Rightarrow \frac{P}{V} =$ const, i.e. $P V^{- 1} =$ const and equivalently $P^{- 1} V =$ const.
