Formulae to calculate heat capacity and heat of fusion for water
To calculate heat capacity in water
Q = mc ∆t
Q = thermal energy in Joules
m = mass in gram
∆t = change in temperature in ° C
c = specific heat capacity in Joules / gram ° C
To calculate heat of fusion in water
∆ Heat of fusion = Q / m
Q = thermal energy
m = mass of melted ice
∆ H fus is in Joules/gram
