The main energy-changes are as follows:
Chemical (in the battery) to electrical
Electrical to sound
In an alarm clock, electrical energy from the battery or power outlet is transformed into mechanical energy to move the clock hands or generate sound energy for the alarm.
In a torch, electrical energy from the battery is transformed into light energy and heat energy by the bulb and may also produce a small amount of sound energy.
The most likely evidence of an energy transformation when a twisted wire breaks is the release of heat. The twisting and turning of the wire causes friction between the wire molecules, which results in the conversion of mechanical energy into heat energy.
The type of transformation taking place when you travel up an escalator is a translational motion, where an object moves from one point to another in a straight line.
Radiant energy -> electrical energy -> thermal energy
kinetic energy
kinnetic
Chemical energy is transferred into kinetic energy. When a person jogs, motion is produced.
Chemical Energy -> Kinetic Energy

The energy in chemical bonds (from food) is turned into:kinetic energy (moving mass), noiseheat (shoes heat up , the runner's body get warm)
The propane gas is being chemically converted to heat energy during the combustion process in the gas stove. This heat energy is then used to cook the food, resulting in a transformation from chemical energy to thermal energy.
