Heat can travel by Convection A hot fluid expands, so is less dense, so rises. Cold fluid takes its place. A convection current can be formed.

Thermal energy and Heat. Thermal energy Thermal energy is the total kinetic energy of all particles in a substance Measured in joules (J) This is not.
By Ollie Docherty and Lauren Moore. Heat energy can move through a substance by conduction. Metals are good conductors of heat, but non-metals and gases.

Work Work done is a measure of the energy transferred. E.g. when lifting a pencil I do work against the earth’s gravity force, energy has been transferred:

Heat transfer. Why does heat transfer happen? Heat is a type of energy called thermal energy. Heat can be transferred (moved) by three main processes:
Motion and Energy. Motion What is Motion? Position is the location of an object. Motion is a change in position over time. Motion has two parts: distance.
Work F The force, F, pushes the box for a short distance. This causes the box to start moving!!!!!! I just don’t have any energy  Whoa!!! Now I do!!!
