- continuously lose their energy till it reaches wall.
- continuously stick to the walls of container.
- are attracted by the walls of container.
- suffer change in momentum when impinge on the walls of container.
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Gas molecules are in constant random motion and collide with the container walls.
Step 2: During a collision, a molecule's velocity changes, meaning its momentum changes.
Step 3: According to Newton's second law, the rate of change of momentum is force. This force per unit area is pressure.
