specific latent heat

- the energy needed to change the state of a 1kg mass from one state to another

the  specific latent heat for changing between a solid,liquid is called the specific latent heat of fusion 

energy = mass (m) X specific latent heat (L) or... E=mL

enery is given in joules, mass in kg and specific latent heat j/kg 

isotopes and nuclear radiation 

-sotopes are different forms of the same element, 

-the number of protons in an atom is its atomic number
