To calculate the energy which needed to any heating, we need to know:

  1. The mass of the heated material (kg), as the water in your problem
  2. The specific heat capacity of the material (J/kg.K), it is a specific quantity for each material.
  3. The change in the temperature according to the heat process (K)

Then, using the relation of heat energy


E=mc Δ
T

Note that: the heat capacity is the multiplication of the mass and the specific heat capacity
