Examples of chemical to mechanical energy?

Answer 1

This question is so short that it's not completely clear exactly what the questioner is after, but I guess they want to know how to convert heat energy to mechanical energy. There are many machines that do this. One obvious example is a steam engine. Some fuel (wood, coal, oil, gas, etc) is burned, the heat is used to boil water and create steam, the steam is used to drive a turbine (or pistons), the energy which is now mechanical, goes through some kind of transmission and turns wheels. A much more simple example is the "dipping or drinking bird", a simple toy made from glass, about 4-5 inches long. here is a link: http://en.wikipedia.org/wiki/Drinking_bird

It's too complicated to fully explain here, but basically it is a "heat engine" which converts heat energy into mechanical energy (movement)

Answer 2

How about digestion? When you eat food, your body takes chemicals from the food and breaks the chemical bonds that hold them together, releasing energy. This energy goes to your muscles, which uses it to do mechanical work, like allowing you to walk, run, etc.

Answer 3

There are many examples of how chemical energy can be transformed into mechanical energy. Perhaps the best known example is the combustion of gasoline in an engine to power an automobile.

Answer 4

We burn energy stored from food in our bonds between atoms. That energy converts into muscle energy to move our bodies.

Answer 5

well haha cuz u dont know it so there lol
