In this video I will explain how a gas molecule absorbs energy through 1) molecular collisions-fast molecule collides with a slow molecule, 2) surface collisions-colliding with a surface, 3) convection-warm air rising from surface heat higher layers, 4) radiation from the Sum, the surface, other molecules; 5) evaporation locks in energy (latent heat of vaporization).
