Question

give an example of one type of energy conversion (change to another form). be sure to explain your example.

question

what does the law of conservation of energy tell us?

Electrical Energy to ThermalEnergy Conversions. 
1. A toaster draws electric current (electrical energy) from a wall outlet and converts these moving electriccharges into heat (thermal energy) in the filaments that turn red hot to cook your toast.

Part 2:
the law of conservation of energy states that the total energy of an isolated system in a given frame of reference remains constant—it is said to be conserved over time. Energy can neither be created nor destroyed; rather, it transforms from one form to another.
