Can someone answer what happens to the enthropy of a gas that is heated?

a maths definition of the change in entropy is:

(heat added)/(temperature at which it is added)

So heating a gas at constant temperature will increase the entropy. Basically, the idea is that as the gas heats up, the distribution of velocities that the constituent particles have becomes broader - the gas molecules have a wider range of velocities. This is the so-called increased disorder that comes with increasing entropy.
