During an exothermic reaction, heat is released to the surroundings, resulting in an increase in temperature. In contrast, an endothermic reaction absorbs heat from the surroundings, causing a decrease in temperature.
In an endothermic reaction, energy is absorbed from the surroundings, causing the surroundings to feel cooler. This is in contrast to an exothermic reaction, where energy is released into the surroundings, causing them to feel warmer.
An exothermic reaction releases heat energy, while an endothermic reaction absorbs heat energy. In an exothermic reaction, the surroundings get warmer, whereas in an endothermic reaction, the surroundings get cooler.
An exothermic reaction in chemistry releases heat energy to its surroundings, while an endothermic reaction absorbs heat energy from its surroundings.
An exothermic reaction releases heat to its surroundings, resulting in a temperature increase. In contrast, an endothermic reaction absorbs heat from its surroundings, causing a decrease in temperature.
Endothermic reactions absorb heat from the surroundings, causing a decrease in temperature, while exothermic reactions release heat into the surroundings, causing a temperature increase. Endothermic reactions require energy input to proceed, while exothermic reactions release energy during the reaction.

An exothermic reaction releases heat to its surroundings, resulting in a temperature increase. In contrast, an endothermic reaction absorbs heat from its surroundings, causing a decrease in temperature.
An endothermic phase change is when the substance absorbs energy from its surroundings (melting, vaporization).In an exothermic phase change the substance releases energy to its surroundings (freezing, condensation)..

Endothermic reactions absorb heat from the surroundings, causing a decrease in temperature, while exothermic reactions release heat into the surroundings, causing a temperature increase. Endothermic reactions require energy input to proceed, while exothermic reactions release energy during the reaction.
Exothermic reactions release energy (usually as heat) into the surrounding environment - endothermic reactions absorb energy from the surrounding environment. Note that exothermic reactions are capable of turning into runaway reactions as the heat of reaction often speeds up the rate of reaction (releasing more heat, etc). Endothermic reactions are, usually, self moderating as a limited amount of energy is capable of being drawn from the surrounding environment.
Endothermic reactions absorb heat from the surroundings, causing a decrease in temperature. In contrast, exothermic reactions release heat into the surroundings, leading to an increase in temperature. Endothermic reactions have a positive enthalpy change, while exothermic reactions have a negative enthalpy change.
The word "endothermic" is made of the parts "endo-" - "within, inside"; "therm" - "heat"; and "-ic" - pertaining to. Therefore the basic meaning of the word describes having heat inside versus "ectothermic" - having heat outside. This word is adapted in biology and chemistry to describe different concepts with a similar base meaning: "endotherm" in biology means animals that generate "heat on the inside" while "endothermic" in chemistry describes a reaction that sucks "heat to the inside".

The reverse of a spontaneous reaction is a nonspontaneous reaction. In a spontaneous reaction, the reaction occurs naturally without any external influence, while in a nonspontaneous reaction, external energy input is required for the reaction to occur.
