What is definition of exothermic?
A type of reaction or process accompanied by the release of heat.
Are all spontaneous processes exothermic?
No. For example ammonium nitrate spontaneously dissolves in water. This is an endothermic process.
How is heat from the sun an exothermic reaction?
Exos= outside , thermos=temperature or heat So within the definition itself it can be known that in exothermic reactions heat is released. In chemical reactions the energy supplied is use in breaking of bonds, but energy is release by making bonds. In exothermic reactions, the energy supplied is sufficient for chemical reaction to occur (to break existing bonds) and the excess energy is given in the form of heat (from making new bonds).If the reaction is exothermic, it means that the total energy it took to break the bonds is less than the total energy released when forming new bonds -- so net energy is released in the form of heat. for example 2H2 +O2 ----> 2H20 which is exothermic reaction. Combustion reactions in general are exothermic reactions.
What is the difference between an exothermic and an endothermic chemical reaction?
Nothing to explain; that is the way EXO- and ENDOthemic reactions are called by definition
When clothes are drying is it an endothermic or an exothermic reaction?
The combustion is exothermic.
What is exothermic definition?
A type of reaction or process accompanied by the release of heat.
What is definition of exothermic?

Why is Burning of a substance a exothermic reaction?
A small amount of energy gets the reaction started, the formation of new compounds releases excess energy. That is the definition of exothermic.
Are all spontaneous processes exothermic?
No. For example ammonium nitrate spontaneously dissolves in water. This is an endothermic process.
Definition of system surroundings?
a system consists of two kinds:the endothermic and exothermic reaction.
What is the definition of 'bird'?
birds are winged, bipedal , exothermic, vertebrate animals that fly and lay eggs.

Is the Combustion of Hydrogen Endothermic?
It is Exothermic
Is the crown a regular polygon?
no its not but if you need to measure the volume of it you drop it in water and measure the amount of water displaced
If it get cold exothermic or endothermic?
Exothermic phenomenon
