Solution

The correct option is B
in hot water is more than that of room temperature water

The speed of molecules in hot water will be more as they possess greater kinetic energy. This kinetic energy of molecules plays an important role in maintaining the temperature high for some time before it cools down. The speed of molecules in cold water is almost nil compared to water at room temperature.
