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'. WebIf heat is absorbed by a one kilogram block of lead, the particles gain energy. Since lead is a solid and the particles are only vibrating, they vibrate faster after being heated. As the...
