Hot objects emits more IR radiation which means the surroundings will get hotter.

You can investigate the absorption of by sticking a peice of wax with a ball bearing stuck in it on the outside of identical pieces of metal just with different colours of paint on the inside. The piece of metal that has the ball bearing falls of first will be have the colour that has quicker absorption.

The intensity is the power per unit area i.e. how much energy is transfered to a given area…
