An energy circus: forms of energy

In the table below are some examples of apparatus commonly used in ‘energy circuses’. For each one, answer to the following questions:
  • What forms of energy are involved?
  • What energy transformations take place?
  • Write down an energy chain to represent what is happening.
The first example in the table has already been done.
 
Example Energy change
1 A battery in a circuit with a bulb Chemical energy -> electrical energy -> light energy ( + heat energy)
2 Winding up a clockwork toy car then letting it go  
3 Using a steam engine to drive a dynamo and light up a lamp  
4 A plant growing  
5 Turning a hand-driven dynamo to make a lamp light  
6 A ball rolling down a ramp  
7 Using an electric kettle to boil some water  
8 An electric motor lifting a load off the floor  
9 An electric bell  
10 A hot cup of water cooling down  
11 An electric motor turning a flywheel, then using the moving flywheel to drive a dynamo and light a lamp  
12 Speaking into a microphone connected to an amplifier and a loudspeaker
