Exothermic means that heat energy is given off from the reaction. In turn this means that the enthalpy (stored chemical energy) decreases. Best example of an exothermic reaction is combustion reactions (reacting with oxygen, or even more simply: burning). The opposite of exothermic is endothermic.

What terms is defined as study of energy and its transformations?
Thermodynamics
What law of thermodynamics states that some useful energy is lost in a reaction?
because partly will be emissed to the environment, which cant be reused. For more information refer to sustainability studies, which are looking, among other things, how heat directed to the environment can be minimised
When energy is given off as heat the physical change is said to be?
Exothermic
What is the relationship between entropy and multiplicity in the context of thermodynamics?
In thermodynamics, entropy and multiplicity are related concepts. Entropy is a measure of the disorder or randomness in a system, while multiplicity refers to the number of ways a system can be arranged while still maintaining the same overall energy. In simple terms, as the multiplicity of a system increases, so does its entropy. This relationship is important in understanding the behavior of systems in thermodynamics.
What are some recommended books on thermodynamics for beginners?
Some recommended books on thermodynamics for beginners include "Thermodynamics: An Engineering Approach" by Yunus A. engel and Michael A. Boles, "Thermodynamics: Concepts and Applications" by Stephen R. Turns, and "Thermodynamics for Dummies" by Mike Pauken.
What does endothermic and exothermic have in common?
The two phenomenons are thermodynamics phenomenons involving heat (absorbing or releasing).
What terms is defined as study of energy and its transformations?
Thermodynamics
Is an exergonic reaction always exothermic, or are there exceptions where the two terms do not align?
An exergonic reaction is not always exothermic. While exergonic reactions release energy, they can be either exothermic (release heat) or endothermic (absorb heat). The terms exergonic and exothermic do not always align because exergonic refers to the overall energy change in a reaction, while exothermic specifically refers to the release of heat.
Does heat move from place to place?
Thermodynamics is the study of heat transfer. Heat moves from place to place from the release of heat (exothermic) and the absorptions of heat (endothermic).
What do exothermic reactions achieve in terms of energy release and temperature change?
Exothermic reactions release energy in the form of heat, causing an increase in temperature.
Does 'exothermic' mean 'releases heat'?
yes
Is condensation an exothermic or an exothermic?
Exothermic Condensation mean the compound loss the kinetic energy that keep them at separate distance from each other and remain in form of gas. It is the release of these energy in condensation thus condensation is exothermic.
Is curium endothermic or exothermic?
The terms exothermic and endothermic are applicable to chemical or physical reactions, not to materials. But because curium is an radioactive element, of course some thermal radiation is emitted.
Physical and chemical changes can be either exothermic or endothermic changes?
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. Ray
What do you need to melt a solid in energy flow terms?
Melting is an exothermic process; we need heat for melting.
What does it mean If heat is produced by a chemical system?
This is an exothermic process.
Is it true that if you are good at math you will fail thermodynamics?
No. Success at math is more likely to improve your skills at thermodynamics. All sciences benefit from some degree of math skill even if only for the ability to think in logical terms.
