Examples of such processes include:
1. Gasoline is ignited in a car engine. As the gasoline burns, it creates small explosions which release heat or thermal energy which moves the pistons and thus the car moves forward.
2. Chemical energy in coal is released as the coal burns to release heat or thermal energy which is used to heat water e.g. in a power plant resulting in production of steam to turn turbines.
3. A butane torch burns gas. As the chemical bonds are broken, the thermal energy released increases the heat energy of a metal which melts and thus two pieces of a metal can be welded together.
