Both, actually. Heat is released by the system (the object or area you're studying), and is absorbed by the surroundings (everything else, not including the system). Typically people are referring to the effects on the system, so in that case an exothermic reaction is a release of heat.
endothermic absorbs, exothermic releases. hence endo-enter, absorb or exo- exit, release energy.

Does endothermic mean to lose energy?
No, endothermic reactions absorb energy from their surroundings, causing a decrease in temperature.
Does the reaction that separates water into hydrogen and oxygen absorb or release energy?
Endothermic reaction is the breakdown of water into hydrogen and oxygen and this cause for energy to be absorbed
What is the type of chemical reaction in which heat energy is absorbed?
An endothermic reaction is a type of chemical reaction in which heat energy is absorbed from the surroundings. This results in a decrease in temperature of the surroundings and an increase in the energy of the reactants.
How do endothermic and exothermic reactions work together to supply energy?
Endothermic reactions absorb energy from their surroundings, while exothermic reactions release energy. In a system where both reactions are occurring simultaneously, the energy absorbed by the endothermic reaction can be used to drive the exothermic reaction forward, allowing for a continuous supply of energy within the system.
Who to you calculate an endothermic?
Endothermic reactions absorb heat energy from the surroundings. To calculate the energy change in an endothermic reaction, you subtract the initial energy of the reactants from the final energy of the products. The resulting positive value indicates that the reaction absorbed energy.
Is evaporation of water release of energy?
Evaporation is an endothermic process, absorb energy.
Is endothermic energy adding or removing?
The meaning of endothermic is "which absorb heat".
How is endothermic reactions differ from exothermic reactions?
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.
What is the opposite of endothermic?
The opposite of endothermic is exothermic. Exothermic reactions release energy in the form of heat to the surroundings, while endothermic reactions absorb energy from the surroundings.
Do chemical reaction absorb energy spontaneously or do they release them?
Some chemical reactions are exothermic, some are endothermic.
How does endothermic reaction absorb energy?
Yes.
Does endothermic mean to lose energy?
No, endothermic reactions absorb energy from their surroundings, causing a decrease in temperature.
Chemical reactions that absorb more energy than they release are called?
It's an endothermic reaction. When more energy is absorbed than released, it has to be absorbed from surroundings. That means the surroundings lose heat as energy is absorbed from them to complete the reaction. This translates to a cooler feeling around the reaction. If you're holding a beaker with an endothermic reaction going on inside it, your hand will feel cool because the reaction is actually absorbing energy from you. An example of an endothermic reaction is combining vinegar and baking soda.
Do all reactions release energy?
No, not all reactions release energy. Some reactions require an input of energy to proceed, and these are called endothermic reactions. Endothermic reactions absorb heat from the surroundings rather than releasing it.
What are chemical rections that absorb energy?
Endothermic Reactions
Which state changes are exothermic and endothermic?
Exothermic state changes release heat energy to the surroundings, such as freezing and condensation. Endothermic state changes absorb heat energy from the surroundings, like melting and vaporization.
Why endothermic reactions cannot be spontaneous reactions?
Endothermic reactions require an input of energy to proceed, which means they do not occur spontaneously. Spontaneous reactions release energy to their surroundings, unlike endothermic reactions that absorb energy from the surroundings. Therefore, endothermic reactions cannot be spontaneous as they need an external energy source to drive the reaction forward.
