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.

physical
What is a process that changes one or more new substances?
I think the answer you're looking for is a "Chemical Reaction". For instance, combining Hydrochloric Acid (HCl) and Sodium Hydroxide (NaOH) will cause a Chemical Reaction resulting in salt water (NaCl + H20).
Is chemical reaction alive?
No. A chemical reaction is not alive.
What is the appropriate definition for chemical reaction in terms of science?
A chemical reaction is a reaction in which elements have their chemical and/or physical properties altered by the end of the reaction.
How can the efficiency of a chemical reaction be expressed?
A chemical reaction is represented by a chemical equation.
What action is an example of a chemical defense in your skin?
One action is an example of a chemical defense in your skin is sweating palms. Sweaty palms are a reaction to stress, thus it's a chemical reaction.
What chemical reaction called when it absorbs energy and causes decrease in temperature?
Probable you think to sweating.
Is perspiration a physical change?
It is a chemical change. Actually "Perspiration" is a noun defined as the chemical product produced by sweat glands. sweating is a physical response to increased body temperature. and the reaction to sweating is the physical cooling that takes place when sweat or perspiration evaporates and gives off heat energy.
What is the results of the hydrolysis reaction?
excess sweating
How can you prevent sweating?
Ummm sweating is a natural reaction from your body to keep you from overheating. I am pretty sure there is no way, or at least no safe way, to prevent sweating.
What causes atom to react with each other?
A chemical reaction
What chemical is formed in a chemical reaction?
The chemical or chemicals formed in a chemical reaction are called the product of the chemical reaction.
Is an icy hot a chemical reaction or a physical reaction?
Its a chemical reaction.
Is bleach a chemical reaction?
