The water in both pans boils at the same time. The water in both pans boils at the same temperature. The 3 L of water gets hotter than the 1 L of water before boiling. The 3 L of water absorbs heat more quickly than the 1 L of water.
I gave my students this multiple choice question: A student heats two pans of water on a stove using the highest setting. One pan contains 1 L of water and the other pan contains 3 L of water. The student heats each pan until the water boils. Which of the following statements best describes what happens to the water in the pans?

Only one answer is correct among these 4 choices:
- The water in both pans boils at the same time.
- The water in both pans boils at the same temperature.
- The 3 L of water gets hotter than the 1 L of water before boiling.
- The 3 L of water absorbs heat more quickly than the 1 L of water.

Could you tell me which one is correct?
