A sample of a gas is kept in a closed container and temperature is increased. Which of the following is true?

A

Pressure is increased because momentum transferred per collision to wall is increased.

B

Pressure is decreased

C

Pressure is increased because frequency of collision is decreased

D

Both (A) and (C) are correct

Text Solution

Verified by Experts

The correct Answer is:
A
`As V prop sqrtT`
So when temperature increases it will increases the momentum of molecules simultaneously frequency of collision also increases which results greater change in momentum per sec.
