    When you cool down a liquid the liquid must radiate heat energy from the liquid to the surroundings. The speed of cooling will depend on the temperature difference between the liquid and the surroundings. Usually, this temperature difference is relatively small.

    When you heat a liquid you use a heating element or a flame to do the job. The heating element will often turn cherry red and the flame will be blue if adjusted properly. The temperature of the combusting gases in a flame is several hundred degrees hotter than the water it is heating. Because of this large difference the water will heat up faster than the water will cool sitting on a cool surface.

    Hope this is helpful.
