Unformatted text preview: Power can be defined as rate of work Power = work/time Watt = 1 Joule / 1 second Intensity - power per surface area Intensity - power/area Wm^-2 = Watt / m^2 Heat energy - form of energy created by internal motion of atoms in a substance Temperature Cannot measure heat directly, but can detect its effect on a substance changes in heat can be detected as changes in temperature when you add energy to a bunch of atoms - move faster & get hotter remove energy - move less and get cooler'...
