What is the specific heat capacity of a 50-gram piece of 100°C metal that will change 400 grams of 20°C water to 22°C?
1 Answer
Explanation:
According to the law of conservation of energy that sates:
Energy cannot be created nor destroyed, we can conclude that the energy lost from the metal is absorbed by water, and therefore;
in here, the metal will lose heat and water will gain heat. Note that the specific heat capacity of water is
Thus,
Now we can solve for the specific heat capacity of the metal and we get:
