Chapter U5, Problem 7RE

Interpretation Introduction

Interpretation: The less energy that is needed to heat up aluminum metal or liquid water needs to be identified.

Concept introduction: Amount of heat required to raise the temperature of 1 gram of a substance by $\text{1}°\text{C}$ is termed as specific heat capacity.

Answer to Problem 7RE

Less energy is required to raise the temperature of aluminum than to raise the temperature of water.

Explanation of Solution

In same amount less energy is required to raise the temperature of aluminum than to raise the temperature of water. This is because water has a high specific heat capacity than alumina.

Conclusion

Of a substance greater the specific heat capacity, less its temperature will grow when it absorbs a given amount of energy. A substance can change its temperature easily if has a low specific heat capacity.
