In my experience, doing 3-6 reps is the sweet spot for this type of training. As this is done in a circuit fashion with incomplete rest, you'll be unable to perform the same loads as during traditional lifting sessions.
The water on your body changes to a gas called water vapor. Water turns into a gas through a process called evaporation. Heat makes water evaporate faster. All air has some water vapor. Tropical rain forests and deserts are both hot.
So as the liquid warms, it makes the water molecules sit further apart from each other as the hydrogen bonds stretch. When the molecules shrink again and give up their energy, this results in it cooling, which the scientists say means that warm water cools faster than cold water and explains the Mpemba effect.
