Question

When we heat a gas-sample from 27°C to 327°C, then the initial average kinetic energy of the molecules was E. What will b the average kinetic energy?

(a) 327E

(b) 300E

(c) 2E

(d) √2E

This question was addressed to me by my school principal while I was bunking the class.

This is a very interesting question from Gases and Reactions in portion Kinetic Theory of Gases of Engineering Physics I

Answer 1

Correct option is (c) 2E

The explanation: E^‘/E=(273+327)/(273+27)=600/300

E^‘=2E.
