Bitesize latent heat
WebChanges in a material's temperature or state of matter are caused by changes to the internal energy. The energy required by different materials depends on their 'heat capacity' and 'latent heat'. WebHeat is energy, which can be transported as molecules vibrate, move and collide into each other Temperature is a measurement of the average motion or kinetic energy of the molecules. One way Black demonstrated …
