Tells us how hot something is and is measured in degrees Celsius (°C). It is also a measure of kinetic energy

Heat
A form of energy measured in joules (J)

Conduction
Transfer of kinetic energy between energy. Energy is transferred through solid materials. The partials vibrate and spread the energy, sometimes there are free electrons which are smaller then normal particles so can move around quicker-

Conduction
- speeding up the whole process. Conduction lets heat out through the walls, floor, roof and windows so we have insulate our homes

Convection
This can happen in a liquid or a gas as the partials can move freely. Cold air can get into the home and then it is heated the is called convection the partials are heated so become less dense and rise when they cool down the partials drop and-

- become more dense this is also called convection and the process is never ending.

Radiation
All objects give out and take in thermal radiation, which is also called infrared radiation. The hotter an object is, the more infrared radiation it emits. Light from the sun reaching earth Infrared radiation is a type of electromagnetic radiation-

-that involves waves. No particles are involved, unlike in the processes of conduction and convection, so it can even work through a vacuumed space. This is why we can still feel the heat of the Sun, although it is 150 million km away from us.
