An Exothermal reaction is a chemical reaction that produces heat making the solution warm or hot. It is the opposite of an Endothemic reaction which makes the solution colder.
Yes, for ex. thermal energy.
Photochemical reaction: a chemical reaction induced by electromagnetic radiations: ul- traviolet, visible, etc.) Thermal reaction: a chemical reaction induced by increasing the temperature (ex.: thermal dissociation, etc.)

If thermal energy must be added to a chemical reaction for the reaction to take place the reaction is endothermic.
This reaction is called thermal decomposition or thermal degradation; example: CaCO3 = CaO + CO2
This is a thermal degradation reaction.

One way to track thermal energy during a chemical reaction is by using a device called a calorimeter. A calorimeter measures the heat released or absorbed during a reaction, allowing you to track the changes in thermal energy.
This is a reaction of thermal decomposition.
Any exothermal reaction.
any reaction that takes up heat cools the surrounding and are thus called ENDOTHERMIC reactions. ex: - thermal decomposition in these reaction a compound takes up heat from the environment to break down into other substances. ex: - CaCO3 ==> CaO + CO2
The thermal decomposition reaction of zinc carbonate can be represented by the equation: ZnCO3(s) → ZnO(s) + CO2(g)
