The correct option to compare a large container of water at 30 degrees Celsius and a small container of water at 30 degrees Celsius is:
A. The large container has more heat energy.
Explanation:
- Heat energy is determined by the amount of substance and its temperature. In this case, both containers have the same temperature (30 degrees Celsius), but the large container contains more water, hence more heat energy.
- The large container, due to its greater volume of water, will require more heat to raise its temperature to 30 degrees Celsius compared to the small container.
- Therefore, even though they are at the same temperature, the large container contains more heat energy due to the larger amount of water it holds.
Remember, the amount of substance and its temperature play key roles in determining the heat energy content.
