1.) Gases diffuse faster when they have high temperature. So the biscuits are just now baked, That's why the odour of the biscuits have high temperature.

2.) No, we can't get that smell again after few hours as the gas when at high temperature will diffuse in much faster way. So the odour of the biscuits will get quickly diffused.
