Question 2: why do we shiver when we go out of the pool on a hot day?
Ans: when the water droplets on our exposed skin change state, they use a lot of energy to make the change of matter, as a lot of energy is required to break the bonds of attraction between the water molecules.Thus, when we get out of the pool, the water uses our body heat to change state, and as heat leaves our body rapidly and suddenly, the muscles in the body shiver to generate more thermal energy.
