Thermal decomposition

 

What is thermal decomposition?

Heat can make some compounds break down. This is called thermal decomposition. It is a type of chemical reaction.

Thermal decomposition reactions need high temperatures. The compounds need a lot of energy to split into simpler substances.

 

The compound that breaks down is the reactant. It can split into elements or other compounds.

Thermal decomposition reactions take in energy from the surroundings. They are endothermic reactions. We use them when we cook and bake cakes.

 

Summary:

 

• Breaking down something with heat is called thermal decomposition.
• When a compound splits into simpler substances because of heat, it is a thermal decomposition reaction.
