A level ideal gases
Please help with question C part (i).
I do not get how to use the above formula, plus isn't that the formula for kinetic energy so how can we use below.
The answer is 12.5J by the way.

Are you able to do (b)? That gives you an equation for the mean energy of one molecule of the gas. Since one of the assumptions of the kinetic theory is that we model molecules as point particles, they cannot rotate, so their entire energy is kinetic energy.
So, you have an equation for the average kinetic energy of a molecule of the gas. How would this change if the temperature was increased by 1 K? And how many molecules have you got?
