an exothermic reaction
an exothermic reaction
... is an exothermic reaction (opposite of 'endothermic')
Exothermic reactions release heat into the system, ie. heat is a product of the reaction and thus the products have less energy than the reactants and the change in enthalpy is negative.Exothermic reactions release heat. Like potassium into water
An exothermic reaction releases energy to its surroundings.
A reaction that releases energy is exothermic.
Exothermic reactions
exothermic reaction releases energy and endergonic reaction absorbs energy
Many substances can "cause" (or participate in) exothermic reactions. An exothermic reaction is a reaction that gives off thermal energy, as opposed to an endothermic reactionwhich requires the input of energy to occur. A classic example of an exothermic reaction is the burning of gasoline in an automobile engine. Gasoline is ignited to induce an exothermic combustion reaction with free oxygen in the air. The reaction causes the release of thermal energy which is converted to mechanical energy as the resulting gasses expand inside the engine's combustion chamber. Excess thermal energy is also released into the cylinder walls of the engine. So much so that your car has a coolant system just to absorb the excess thermal energy into a water-based coolant, and dissipate it from your radiator. Lots of heat energy being given off=exothermic reaction. And again, there are many different exothermic reactions involving many different substances.
It is called an exothermic reaction. Example: a burning candle
The energy release of an exothermic reaction is released to the surroundings.
For example in an exothermic chemical reaction.
