Determine the amount of heat required to heat 3 kg of water to the boiling point if the initial water temperature is 15 degrees and the specific heat capacity of water is 4200 J / kg * K.

Data: m (mass of water taken for heating) = 3 kg; t0 (initial temperature of taken water) = 15 ºС.

Reference values: t (temperature at which boiling begins) = 100 ºС; by condition C (specific heat capacity of water) = 4200 J / (kg * K).

You can determine the required amount of heat using the formula: Q = C * m * (t – t0).

Let’s make the calculation: Q = 4200 * 3 * (100 – 15) = 4200 * 3 * 85 = 1,071,000 J ≈ 1.1 MJ.

Answer: You need 1.1 MJ of heat.
