Question

Initial temperature of water before heating

Answer 1

Mass of water (m) = 1000 g. Specific heat capacity of water, c = 4.19 J /g.°C. Initial temperature of water = 20°C. Final temperature of water is its boiling point, which is equal to 100°C.

Answer 2

The initial temperature can be calculated with the help of

Q = m * c * ΔT

Q = m * c * (T - t0)

It will depend on the energy which will help in determining the actual temperature of water.

On the other hand, you will require a specific heat of the water along with the energy consumed.
