Temperature and kinetic energy relation

Practice Question Solving
1

The temperature of a gas in a non-expandable container rises from 290 K to 320 K.
Which of the following will increase?

  1. Volume of the gas
  2. Pressure of the gas
  3. Kinetic energy of the molecules
  4. Mole of gas

A. 2 and 3 only

B. 3 and 4 only

C. 2 and 4 only

D. 1 and 2 only

E. 1 and 4 only

The correct answer is D. May I know why the kinetic energy is not taken into account for this ?

2

I’m not exactly sure why the answer is D as it should be A,
2 and 3.
Volume wouldn’t increase as it is in a non expandable container and kinetic energy would definitely increase if pressure increases as the pressure increases due to the increased no. of collisions per unit time which means the kinetic energy is higher.
Could someone clarify this?

I completely agree, should be A
