The two terms are probably used most often to describe chemical reactions - whether or not they absorb or require heat (endothermic) or create release heat (exothermic). However, since the terms simply mean "absorbing heat", and "giving off heat", they can be used to describe any such event, physical, chemical or nulear.

What is an exothermic process?
An exothermic change is a change that releases heat. Combustion is an exothermic chemical reaction.Adding water to sulfuric acid releases heat, called exothermic heat of mixing. Exothermic changes are the opposite of endothermic changes that absorb heat when they take place.
Is changes in energy a chemical change?
Changes in energy themselves are not considered chemical changes. Instead, changes in energy may occur as a result of a chemical change taking place, such as in an exothermic or endothermic reaction where energy is either released or absorbed.
How do you classify a chemical reaction?
Chemical reactions can be classified based on the type of reaction (e.g., synthesis, decomposition, single replacement, double replacement) or the energy changes involved (e.g., exothermic, endothermic). Classification helps in understanding the underlying principles and predicting the products of reactions.
Is plasma exothermic or endothermic?
Plasma itself is not classified as exothermic or endothermic; these terms describe the heat exchange during phase changes or chemical reactions. However, the process of ionizing a gas to create plasma is typically endothermic, as it requires energy input to strip electrons from atoms. Conversely, when plasma cools and recombines into a gas, it can release energy, making that process exothermic.
Why is salt endothermic?
Salt is not inherently endothermic; rather, it can exhibit endothermic properties in certain situations. For example, when salt dissolves in water, it can absorb heat from the surroundings, leading to an endothermic process. This is because breaking the ionic bonds in salt requires energy, which is supplied by the surroundings in the form of heat.
Are chemical reactions accompanied by chemical changes in energy?
Yes. Refer to endothermic and exothermic reactions to learn more.
What contrast endothermic and exothermic changes?
Exothermic: release of heat Endothermic: absorption of heat
Which state changes are exothermic and endothermic?
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
Is exothermic a physical or a chemical change?
It can be either. Some exothermic processes, such as combustion, are chemical changes while others, such as condensation, are physical.
What is an exothermic process?
An exothermic change is a change that releases heat. Combustion is an exothermic chemical reaction.Adding water to sulfuric acid releases heat, called exothermic heat of mixing. Exothermic changes are the opposite of endothermic changes that absorb heat when they take place.
What are the ways that heat takes part in a chemical changes?
Heat can be involved in a chemical reaction that is endothermic(absorbs heat) or that is exothermic(releases heat)
Is changes in energy a chemical change?
Changes in energy themselves are not considered chemical changes. Instead, changes in energy may occur as a result of a chemical change taking place, such as in an exothermic or endothermic reaction where energy is either released or absorbed.
Is burning a physical Change changes?
It's an exothermic reaction (oppose to an endothermic reaction). It's combustible reaction, (this is an example of chemical reaction) where a substance must combine with oxygen to produce, heat and light; or Burn.
What two kinds of energy changes can take place during a chemical reaction?
Two types of energy changes that can occur in a chemical reaction are (1) endothermic and (2) exothermic. Endothermic is where energy is added to the system and exothermic is where energy is given off by the system.
How do you classify a chemical reaction?
Chemical reactions can be classified based on the type of reaction (e.g., synthesis, decomposition, single replacement, double replacement) or the energy changes involved (e.g., exothermic, endothermic). Classification helps in understanding the underlying principles and predicting the products of reactions.

Conversely, when plasma cools and recombines into a gas, it can release energy, making that process exothermic.
Contrast the forming and breaking of chemical bonds in terms of energy changes?
The formation of chemical bonds releases energy. It is an exothermic process. The breaking of chemical bonds takes energy. It is an endothermic process.
