Why does the temperature of a substance not increase if it’s changing state
The energy that you are providing is being used to weaken or break bonds holding particles together rather than increasing the particles internal energy
What is the definition of Specific latent heat
The energy required to change 1kg of a particular substance from one state to another without changing it’s temperature
What are the two specific latent heats
Specific latent heat of fusion and vaporisation
What is the meaning of specific latent heat of Vaporisation
Energy change when a substance changes between a liquid+gas
What is the meaning of specific latent heat of fusion
Energy change when a substance changes between a solid+liquid
When a substance is being cooled what is the differebce in what specific latent heat is
It isn’t the energy required to break bondsit’s the energy released when bonds are formed
What is the equation for specific latent heat
Energy=massXspecific latent heat
