Calculate the energy required to vapourise 50g of water Initially at 80¡ãC if the specific heat capacity of water is 4.2 J/g.k. (specific latent heat of vapourisation of water is 2260 J/g)

• physics -

add the heat required to get from 80C to `100C, then to vaporize the 50g.

I still don't understand.
