The skin is cooled through evaporation.
An exothermic reaction<span> is a chemical </span>reaction<span> that releases energy by light or heat. It is the opposite of an </span>endothermic reaction<span>. Expressed in a chemical equation: reactants → products + energy.</span>
There are many answers to your question but one way is the evaporation cycle.
All isotopes of hydrogen will always contain one proton, as a change in the amount of protons will change the substance. Assuming all isotopes aren’t ions and therefore don’t have a charge, then each of these isotopes has one electron. The only difference between them is the amount of neutrons to account for the different atomic masses.
H1
one proton
one electron
zero neutrons
H2
one proton
one electron
one neutron
H3
one proton
one electron
two neutron
