All examples involve chemical energy except a. working muscles using food. b. burning a candle. c. coasting downhill on a bike

Coasting downhill on a bike

Explanation:

The example that involves chemical energy are working muscles using food and burning a candle. In both of these processes many biochemical processes are involved i.e. mobilization of energy from glucose stores etc.

Coasting downhill on a bike does not involve any chemical energy. There exists an energy change i.e. potential energy is converting to kinetic energy.

Hence, the correct option is (c) "coasting downhill on a bike".

okay i have so many questions. but the big one here is: um wt..f is this mess? ?
