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.
This change of phase (from a liquid to a gas) requires heat, called the latent heat of condensation. When water evaporates, it removes heat, lowering the temperature of the surface. For both water and land surface, most of this heat energy comes from the surface, not from the air. Evaporative cooling, along with convection, helps keeps the surface of the Earth from getting too hot. Interesting facts:
