Heat flow

Heat flow

Heat flow. Heat is energy: measured in Watts ( = J/s) Temperature is the amount of heat in a material. Measured in degrees Celsius (C o ) Measured in Kelvin (K) 0 K (-273 C o )= material with no heat. Vibration of molecules in a substance. Electromagnetic radiation. Heat flow.
