# When a trebuchet counterweight is hoisted by soldiers, what form of energy is transferred into the machine as work?

The correct answer to the question is : 1) The water in pot X has more kinetic energy than water in pot Y.

EXPLANATION:

As per the question, the temperature of pot X = 56 degree Fahrenheit.

The temperature of water pot Y  = 49 degree Fahrenheit.

We know that temperature is a measure of average kinetic energy of energy of a system. The system having more average kinetic energy must have at a greater temperature as compared to the system having low average kinetic energy.

The potential energy of a system has no role in case of temperature.

If the temperature of two systems are equal, it means the average kinetic energy of two systems are equal.

When we provide heat to a body, the average kinetic energy of a body increases. So, its temperature increases. When the substance undergoes phase change, the average kinetic energy of the body remains constant.That’s why the temperature remains constant as long as total substance is not converted into other state.

Hence, the correct statement is that water in pot X has more kinetic energy than water in pot Y.
