What does one mean by exothermic and?

Reaction or process is heat generating or absorbs heat. It is not necessary that an endothermic reaction absorbs or generates heat. However, an endothermic reaction is one in which the absorption or generation of heat is spontaneous. In contrast, an exothermic reaction is one in which the absorption or generation of heat is spontaneous and is driven by an increase in entropy.

What does exothermic mean in biology?

An exothermic reaction, or reaction that produces heat, is one where the sum of the enthalpy change is negative. In other words, when things burn, they lose energy to the surroundings, which is why we describe fire as “burning” or “consuming” energy.

What does exothermic mean in chemistry?

Exothermic is a reaction that generates heat. If a reaction absorbs more heat than it gives off, it is an endothermic reaction. If a reaction produces heat, it is an exothermic reaction. Both endothermic and exothermic reactions occur naturally in living organisms and the environment.

What does exothermic mean in physics?

A reaction is called exothermic when the heat energy produced during the chemical reaction (or the sum of the heat produced during the chemical reaction plus the heat absorbed to do the chemical reaction work) is greater than the heat absorbed by the surroundings to do the same amount of work. The heat energy that is produced is given off as the reaction proceeds.

What does exothermic mean in science?

Exothermic means that something absorbs or gives off heat. A reaction is exothermic when the amount of heat absorbed or given off is greater than the amount of heat required to carry out the reaction. This means that the net effect is an increase in the overall energy of the system.
