The main energy-changes are as follows:
Chemical (in the battery) to electrical
Electrical to sound
Electrochemical (Radio's battery) ---> Electrical (Power to the radio) + Heat (Waste Byproduct) + Sound + Light (LED's / Radio display)
When you turn on a heater, electric energy transforms to heat energy
eelectrical energy to9 sound energy

Electrical energy
potential --.
Radiant energy -> electrical energy -> thermal energy
The transformation of energy take place in hydropower plant includes:Potential energy -> kinetic energy-> electrical energy
Itβs C. Stored chemical energy -> kinetic energy
Mechanical energy is wasted due to friction. The wasted energy is converted into heat.

chemical energy to heat energy
Chemical Energy -> Kinetic Energy
Chemical energy is transferred into kinetic energy. When a person jogs, motion is produced.

Kinetic energy
Mechanical energy is wasted due to friction. The wasted energy is converted into heat.
The energy in chemical bonds (from food) is turned into:kinetic energy (moving mass), noiseheat (shoes heat up , the runner's body get warm)
