According to the kinetic theory of gases, the pressure exerted by a gas on the walls equals.
A
Momentum imparted to the walls per unit area.
B
Change in momentum per unit volume.
C
Change in momentum imparted to the walls per unit area.
D
Rate of change of momentum imparted to the walls per second per unit area.
Verified Correct Answer: D.
Physical Principles & Numerical Solution
D. Rate of change of momentum imparted to the walls per second per unit area. (Pressure = force/area = (rate of momentum change)/area from molecular collisions.)
