Oddly enough, evaporation is endothermic. To tell the difference, simply ask yourself, must heat be added or taken away for a phase change to occur. If heat must be added it is endothermic, if heat must be taken away it is exothermic. In the case of evaporation in most cases you must raise the temperature for a substance to evaporate, thus it is endothermic.

Sweating itself is not a chemical reaction. Sweating is the body's mechanism to regulate body temperature by releasing sweat, which is mainly composed of water and electrolytes. However, the process of sweat production by the sweat glands involves cellular processes within the body, which are chemical reactions.
It is neither Perspiration id fluid that the body releases to cool it. Exothermic means a chemical reaction that gives of heat. Endothermic is a chemical reaction that uses heat.

No, Evaporation is an endothermic process: the evaporating substance must absorb energy to become a gas.
No. A chemical reaction is not alive.
A chemical reaction is represented by a chemical equation.
A chemical reaction is a process that changes one or more substances into new substances with different chemical properties. This involves the breaking and formation of chemical bonds between atoms or molecules.
Combustion is a hemical reaction.
This chemical reaction is called dehydration.
