State the first law of thermodynamics and provide an example to illustrate it.

• The first law of thermodynamics states that energy cannot be created or destroyed, only transformed from one form to another.

• The first law of thermodynamics states that energy can only be transformed from one form to another, but cannot be conserved.

• The first law of thermodynamics states that energy can be created and destroyed, with no limitations.

• An example to illustrate this law is the conversion of mechanical energy into sound energy in a musical instrument.
