Question

Calculate the energy required in joules to raise the temperature of 450 grams of water from 15°C to 85°C. (The specific heat capacity of water is 4.18 J/g/°C)

Answer 1

The energy required in joules to raise the temperature of 450 grams of water from 15°C to 85°C:

$$Q=mc(T_2-T_1)$$

$$Q=(450)(4.18)(85-15)=132000\ J$$
