PLEASE HELP ME WITH ONE QUESTION

If 1000 J of heat energy is lost from a piece of hot metal which is placed into a cup of cool water, how much energy is gained by the water?

Answer 1

1000J

Step-by-step explanation:

According to the law of calorimetry;

Heat lost by cold substance = Heat gained by hot substance

If 1000 J of heat energy is lost from a piece of hot metal,

heat lost by hot substance = 1000J

Since we are to determine how much energy is gained by the water, using the law

Heat lost by hot metal = heat gained by the water

Hence heat gained by the water = 1000J
