The boiling point, melting point, specific heat liquid, specific heat solid, ΔHvap and ΔHfus are given. Determine how many kJ of heat (ΔH) are needed to melt or freeze x grams at it’s normal boiling point. This solver works for both questions asking for melting the sample and questions asking to freeze the sample.
