Chemical reactions that involve bond-breaking tend to absorb energy from the surroundings, making the surroundings cooler. Chemical reactions that involve making bonds release energy, which makes the surroundings hotter. An example of a temperature change in a chemical reaction is when a burning fire produces heat.
A positive change in enthalpy for a chemical reaction indicates that the reaction is endothermic, meaning it absorbs heat from its surroundings. This typically results in the surroundings feeling cooler.
Endothermic reactions absorb heat from their surroundings, resulting in a decrease in temperature in the room where the reaction takes place. This can make the room feel cooler as the reaction uses up the heat energy present in the environment.
Much warmer.
Endothermic reactions take in heat from the surroundings (and make it cooler), exothermic reactions give out heat to the surroundings making it hotter. Get too close to a sparkler and you'll find it is very hot! This is because it is an exothermic reaction.
In an exothermic reaction, energy is released in the form of heat, making the surroundings warmer. In contrast, an endothermic reaction requires energy input from the surroundings to proceed, making the surroundings cooler as it absorbs heat.
The surroundings become warmer when propane reacts with oxygen as it undergoes combustion, releasing heat energy as a byproduct of the reaction.

Chemical reactions that involve making bonds release energy, which makes the surroundings hotter. An example of a temperature change in a chemical reaction is when a burning fire produces heat.
If energy is released as a result of a process, an exothermic change has taken place. If a constant input of energy is required to drive a physical or chemical change, the change is described as endothermic.
A positive change in enthalpy for a chemical reaction indicates that the reaction is endothermic, meaning it absorbs heat from its surroundings. This typically results in the surroundings feeling cooler.

In a blank reaction, energy is absorbed from the surroundings, causing the surroundings to feel cooler. This is an endothermic reaction because energy is required for the reaction to occur. Examples include melting ice or mixing ammonium nitrate with water.
No, they are cooler.
When ammonium nitrate dissolves in water, it absorbs energy from the surroundings to break the bonds between its ions. This absorption of energy causes the surroundings to become cooler, leading to a decrease in temperature.
