How many joules of heat are needed to melt 50 g of ice at 0°C and then warm the liquid to 65°C? heat of fusion of ice = 334 J/g specific heat of water = 4.184 J/g°C specific heat of ice = 2.03 J/g°C heat of vaporization of water = 2260J/g

Explanation:

Hello,

In this case, in this heating process, we should consider two steps which have their own associated enthalpy for the same mass of water:

1) Melting of ice at 0 °C.

2) Heating of liquid water from 0 °C to 65 °C.

Therefore, the total needed heat turns out:
