I gave my students this multiple choice question: Paul observes four different samples of water. He records the temperature and volume of each sample. Which of his samples contains the greatest amount of thermal energy?

Only one answer is correct among these 4 choices:
- 100 mL of 10°C water
- 100 mL of 25°C water
- 5 liters of 10°C water
- 5 liters of 25°C water

Could you tell me which one is correct?

5 liters of 25°C water
