At what temperature will the molar kinetic energy of `0.3 mol` of `'He'` be the same as that of `0.4 mol` of argon at `400 K`?

A

700 K

B

500 K

C

800 K

D

400 K

Text Solution

Verified by Experts

The correct Answer is:
D
Kinetic energy of a gas depends upon the temperature. At constant temperature, kinetic energy of all gas molecules is same.
