Transfer of heat through a solid (particles gain kinetic energy, hit neighbouring particles and transferring some of the energy to them, this happens throughout the solid)

Metals are good conductors because

delocalised electrons can travel more and pass on the energy quicker throughout the solid


Transfer of heat energy through fluids (liquids and gases) - hot fluid particles have more energy and so expand and rise, cool fluid particles have less energy so fall —> convection current)


Heat can transfer from place to place in the form of infrared radiation

Force =

Mass x acceleration

Kinetic energy =

0.5 x mass x velocity squared

Elastic potential energy =

0.5 x spring constant (k) x extension squared (e)

Work done (energy transferred) =

Force x distance

Specific heat capacity

The amount of energy to required to change the temperature of 1kg of a substance by 1 degrees Celsius

Specific heat capacity equation

Energy = mass x specific heat capacity x change in temperature

Power =

Energy transferred / time
