Endothermic reactions absorb energy from the surroundings and typically feel cold to the touch, while exothermic reactions release energy into the surroundings, often in the form of heat, and feel warm or hot.

Endothermic reactions absorb energy from the surroundings and typically feel cold to the touch, while exothermic reactions release energy into the surroundings, often in the form of heat, and feel warm or hot.
Endothermic and exothermic reactions differ in terms of heat energy exchange. Endothermic reactions absorb heat from the surroundings, causing a decrease in temperature, while exothermic reactions release heat, leading to a temperature increase. In an endothermic reaction, the products have higher energy content than the reactants, requiring an external heat source. Exothermic reactions, on the other hand, release energy as products form, often resulting in a temperature rise. Examples of exothermic reactions include combustion and many chemical reactions used for heating. Understanding these concepts is crucial in fields such as chemistry and thermodynamics, influencing reactions in various processes.
