Ed records the temperature of two pots of water. The pots are the same size and material. Pot X has a temperature of 56 degrees Fahrenheit, and pot Y has a temperature of 49 degrees Fahrenheit.

Both pots contain water, so the water has the same specific heat in each pot. Since the pots are the same size and material, the warmer water in pot X (56°F versus 49°F) has greater average molecular kinetic energy. Therefore, choice A is correct: the water in pot X has more kinetic energy.
