when you wind up a clockwork toy, the spring inside of it twists and that called strain energy, then when you let go of the toy the spring unwinds and toy toy moves which is kinetic energy and it may also make a sound as well.

What type of energy changes take place when a candle burns?

When a candle burns, the chemical potential energy stored in the wax is converted into heat and light energy through the process of combustion. The heat energy generated causes the surrounding air to warm up, while the light energy is emitted as a visible flame.


What energy changes take place in a solar cooker?

In a solar cooker, solar energy (light and heat) is absorbed by the reflective surface and converted to heat energy. This heat energy is then transferred to the food in the cooker, causing it to cook or heat up.


What energy changes take place during the generation of electricity?

During the generation of electricity, energy changes occur as different forms of energy are converted. Typically, the process involves converting mechanical energy (e.g. from spinning turbines) or chemical energy (e.g. from burning fuels) into electrical energy through generators or other systems. Heat energy may also be produced as a byproduct of these energy conversions.


What energy changes take place in a torch?

In a torch, chemical energy stored in the battery is converted into electrical energy when the torch is turned on. The electrical energy is then converted into light and heat energy when the current passes through the bulb's filament, producing the light that is emitted from the torch.


What energy changes take place in the boiler?

In a boiler, potential energy from fuel is converted into heat energy through combustion. This heat energy is then transferred to water, raising its temperature and converting it into steam. The steam carries this thermal energy to turbines, where it is converted into mechanical energy to generate electricity.
