2 - The principles used in air conditioning are basically the same as those that are used by the human body to cool itself.

3 - Although hydrogen gas is highly explosive, it is used to cool steam generators at the plant because it has a high capacity for heat and is more efficient than using air.

4 - Fish often spend much of their time in the deep, cool waters of a lake unless oxygen levels there become depleted by decomposers.

5 - Exercising in extreme temperatures provides an added stress on our body to cool down.
