Examples for exothermic change are burning of fuels or coal, burning of a fire cracker and glowing of an electric lamp.
No because in an exothermic change energy is released not taken in. Melting would be an example of exothermic change.
This process is called exothermic reaction, where energy is released in the form of heat. It typically involves a change from a higher energy state to a lower energy state, resulting in the release of energy to the surroundings. An example would be the solidification of molten lava into solid rock, releasing heat energy in the process.
The phase change of sublimation is not correctly paired with the sign of its change in enthalpy. Sublimation involves the transition from solid to gas phase without passing through the liquid phase, and it is an endothermic process where heat is absorbed. The other phase changes—melting (endothermic), freezing (exothermic), vaporization (endothermic), and condensation (exothermic)—are correctly paired with the sign of their change in enthalpy.

The process of making Jello is an exothermic change because energy is released in the form of heat as the gelatin sets and solidifies.
No because in an exothermic change energy is released not taken in. Melting would be an example of exothermic change.
These are exothermic reactions.
It's a exothermic reaction because heat and light is being released.

Exothermic
An endothermic change requires heat, and an exothermic change releases heat.
endothermic change
An exothermic reaction involves the release of heat into a system. The burning of a candle is combustion reaction. Combustion reaction release heat, and this can be detected and measured by the burning of a candle's wax. From these testable observations it is determined fact that candle burning is indeed exothermic.
Burning a match is an exothermic change because energy is being released.
