Endothermic reactions increase their enthalpy by absorbing heat
Endothermic reactions absorb heat from their surroundings, making them feel cold.
An exothermic reaction would feel warm or hot if you put your hands near it, as it releases heat to its surroundings. An endothermic reaction would feel cool or cold if you put your hands near it, as it absorbs heat from its surroundings.
An endothermic reaction feels cold because it absorbs heat from its surroundings. This can sometimes give the sensation of cooling or a decrease in temperature.
An endothermic reaction is one that consumes heat.
An example of a reaction that gives out a lot of heat is the combustion of gasoline in engines. This reaction releases a large amount of energy in the form of heat and light.
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.

An endothermic reaction is one that consumes heat.
During an endothermic reaction, heat is absorbed from the surroundings, causing the reaction to feel cold. The reactants have less energy than the products, so energy is absorbed to form the products. In an exothermic reaction, heat is released into the surroundings, making the reaction feel hot. The reactants have more energy than the products, so energy is released during the reaction.
Endothermic means more energy goes into a reaction than the reaction gives off. It tends to absorb heat (feel cool).
A cold pack creates a endothermic reaction when the chemical reacts, which means that energy is taken from the surrounding, which makes the packaging cold. it is the opposite with a heat pack, an exothermic reaction is created which releases the energy into the surrounding creating the heat. Hope this helped.
Exothermic reaction gives free heat (energy).
An example of a reaction that gives out a lot of heat is the combustion of gasoline in engines. This reaction releases a large amount of energy in the form of heat and light.
Heat generally speeds up the reaction, while cold will slow it down. The enzymes in the cold are frozen.
An example of a chemical reaction that absorbs heat is the reaction between baking soda (sodium bicarbonate) and vinegar (acetic acid) to produce carbon dioxide gas. This reaction is endothermic, meaning it absorbs heat from its surroundings, causing the mixture to feel cold to the touch.
