Answer:

14,700 joules

Explanation:

We are given;

  • Mass  of water as 175 g
  • Initial temperature of water as 15°C
  • Final temperature of water as 35°C

We are required to determine the amount of energy absorbed

We need to know that;

Heat energy absorbed is given by the formula;

Heat = Mass × change in temperature × Specific heat

In this case;

Change in temperature = 35°C - 15°C

                                        = 20 °C

Specific heat of water is 4.2 J/g°C

Therefore;

Heat = 175 g × 20°C × 4.2 J/g°C

         = 14,700 joules

Therefore, the amount of heat absorbed is 14,700 joules
