Endothermic reaction
For endothermic reactions Hfinal > Hinitial and DH is positive (+DH)
It can be for example melting ice, or vaporising Rubbing Alcohol.---------Change of phases are not chemical reactions !Nothing to explain; that is the way EXO- and ENDOthemic reactions are called by definition
Endothermic reaction
the name your looking for is an "exothermic" reaction, one in which heat energy is released to the surrounding atmosphere the other is an endothermic, which absorbs the energy around it making it a "cold" reaction
'Thermic' means heat. Thus an 'exothermic' reaction produces heat, while an 'endothermic' reaction absorbs heat.
An endothermic reaction is one that absorbs heat from the surroundings.
An endothermic reaction.
Endothermic reaction
Endothermic reactions.
An endothermic reaction absorbs heat, an exothermic reaction releases heat.
An Endothermic reaction. If you touch the reaction vessel it will feel cool/cold, as it is taking in heat energy. By contract an Exothermic reaction is one that gives out heat. If you touch the reaction vessel it will feel warm/hot as it is liberating heat energy.
Yes. A chemical reaction which absorbs heat during the reaction. The opposite to exothermic which releases heat during the reaction.

Endothermic Reaction
an endothermic reaction is any chemical reaction that absorbs heat from its environment.
An endothermic reaction.
No, a chemical reaction that absorbs energy is called an endothermic reaction. The transfer of heat from the surrounds into the substance. In reactions, energy is always CONVERTED, not created which means that nothing can be converted i.e. heat to chemical if there is no heat or initial energy.
