The heat used in phase changes is calculated by multiplying the mass of the substance by the energy of the phase change. In this case, for liquid to boil, we would find total heat by multiply the mass of liquid by the latent heat of vaporization (Hvap). If we are instead given the Hvap and the total heat of 1 kJ, we would divide 1 kJ by the Hvap (which is usually in kJ/kg) to get the mass of liquid boiled (in kg).

I think is 5 because you use density is found by mass divide by volume.
ok, here is a sentence for you:
Frost wedging is a process that is an occurrence when ice forms in a tiny crack of a rock and then i breaks slowly melting away and eroding the surface of the rock or mineral etc.
I hope this helps you!
De Broglie predicted that in his equation. The ball is not a particle.<span>
