Always endothermic. Liquids absorb heat from the surroundings through evaporation, and keeps continuing this to regain lost energy. This produces a cooling effect in the surroundings.
Water evaporation is an endothermic process.
Evaporation is an endothermic process.
It will be an endothermic process because the beaker becomes cool after evaporation.
No, evaporating is not always an exothermic reaction. Evaporation is the process of a liquid turning into a gas, and whether it is exothermic or endothermic depends on the specific conditions such as temperature and pressure.
Physical endothermic change because it uses energy (taking up heat)
Evaporation of alcohol is an endothermic process because it requires energy to break the intermolecular forces holding the alcohol molecules together. This energy is absorbed from the surroundings, resulting in a cooling effect.
EXOTHERMIC: any combustion ENDOTHERMIC: evaporation of liquids
Water evaporation is an endothermic process.
It is an endothermic process.
Exothermic
Evaporation is an endothermic process.
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
It will be an endothermic process because the beaker becomes cool after evaporation.

When something burns it gives off heat. Therefore, it is exothermic.
Evaporation is an endothermic process.Condensation is an exothermic process.
