Which state changes are exothermic and endothermic?
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
Is burning alcohol endothermic or exothermic?
When something burns it gives off heat. Therefore, it is exothermic.
Is liquid exothermic or endothermic?
Depends, Liquid can be both endothermic and exothermic, for example water, if you freeze water and put it in room temperature it will be endothermic, meaning it will absorb the heat form the room. And if you Boil water and put it in a cold place it will become exothermic because its releasing the heat.
Is a puddle of water evaporating endothermic or exothermic?
The evaporation of a puddle of water is an endothermic process because it requires energy input to break the hydrogen bonds between water molecules. Energy is absorbed from the surroundings, causing the temperature of the puddle to decrease as the water evaporates.
What is the opposite of endothermic?
Exothermic. An endothermic reaction absorbs heat , while an exothermic reaction releases it.
What are everyday uses of exothermic and endothermic?
EXOTHERMIC: any combustion ENDOTHERMIC: evaporation of liquids
Is evaporating rubbing alcohol on skin endothermic?
Water evaporation is an endothermic process.
Evaporating alcohol endothermic or exothermic?
It is an endothermic process.
Is burning alcohol an exothermic or endothermic process?
Exothermic
A puddle of water evaporates is an example of exothermic or endothermic?
Evaporation is an endothermic process.
Is alcohol evaporation endothermic or exothermic?
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.
Which state changes are exothermic and endothermic?
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
Is evaporation an exothermic or endothermic process explain?
It will be an endothermic process because the beaker becomes cool after evaporation.
Is evaporating always an exothermic reaction?
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.
Is evaporation os exothermic or endothermic process.explain?
Physical endothermic change because it uses energy (taking up heat)
Is burning alcohol endothermic or exothermic?
When something burns it gives off heat. Therefore, it is exothermic.
Is it true that evaporation and condensation take place when water gains heat energy?
Evaporation is an endothermic process.Condensation is an exothermic process.
