Thermal decomposition of carbonates

Thermal decomposition , as we have studied in the First Chapter raising the temperature of a solid causes its melting into a liquid form , but in some substances before melting , another process might happen  which is the breaking down of the substance into more simple compounds 

In our example here the calcium carbonate (limestone) here is broken down into Calcium oxide ( lime) and carbon dioxide gas produced

since heat is used we call this decomposition ➡️ Thermal decomposition
