Answer:
3.1 Lighted Candle
The heat from the wick melts the wax which gets absorbed in the wick and then gets burnt (which is really oxidation) to produce heat energy as well as light energy. The energy transforms from chemical energy to heat and light energy.
3.2 A moving car
The internal combustion engine in the car converts the potential chemical energy in gasoline and oxygen into thermal energy which is transformed into the mechanical energy that accelerates the vehicle (increasing its kinetic energy) by causing the pressure and performing the work on the pistons.
3.3 Flashlight
When the flashlight is turned on, the chemical energy is first transformed into electrical energy and then into light energy. CHEMICAL bonds. It is released during a chemical reaction (change).
3.4 Electric Fan
The fan converts electric energy into kinetic energy that does work, and it converts some electric energy into heat.
3.5 A man doing exercise
When the energy begins to put you into work, the chemical energy is now a potential energy is being transformed into kinetic energy. ... Say the exercise involves riding a bike, the kinetic energy is now being transferred into the pedal in the form of mechanical energy.
