In an endothermic reaction, energy is __ no change absorbed. released.

## Step 1<br />An endothermic reaction is a type of chemical reaction where the system absorbs energy from its surroundings. This energy is usually in the form of heat. <br /><br />## Step 2<br />The term "endothermic" is derived from the Greek words "endon" (meaning "from within") and "thermikos" (meaning "heat"). This indicates that the reaction absorbs heat from its surroundings.<br /><br />## Step 3<br />In contrast, an exothermic reaction is one where energy is released to the surroundings, usually in the form of heat.<br /><br />## Step 4<br />In an endothermic reaction, the energy required to break the bonds in the reactants is greater than the energy released when new bonds are formed in the products. This results in a net absorption of energy.
