Professor Turner warned his first year university class, “…it is internal energy. If I catch any of you calling it ‘heat’, I will personally come out and thump you.” Can you explain the difference so that one of the professor’s students will not get into trouble with the professor?
Internal energy is the energy contained by the molecules in a material. This energy is shown by the vibration of the atoms. Heat is a flow of energy through a material.
Internal energy can be stored (for example in a hot water bottle, or night storage heater)
Heat cannot be stored. For storage, heat is converted to internal energy.
