what is the Specific heat capacity value for Paraffin?

2.25kg of ice, initially at −40
∘C, is heated using a 3.2kW heater without loss to the surroundings. How much more time elapses before the water reaches boiling point? Give your answer in seconds.

A mass of 0.35kg of ice at −15∘C is lowered into an insulated beaker containing 0.61kg of water at 59∘C. What is the temperature after equilibrium has been reached? Give your answer in ∘C

If you still need help, guides are given below:
Energy lost by the water at 59 °C as the temperature decreases from 59 °C to the equilibrium temperature equals energy gained by the ice to increase the temperature from ‒15°C to 0°C + energy gained by the ice to melt at 0°C + energy gained by the water (from 0.35 kg of ice) to increase the temperature from 0°C to the equilibrium temperature.
