Describing a bottle opener and the way it functions.
My question is deceptively simple seeming, all I have to do is describe how a bottle opener opens a bottle.
I think I have a good explanation worked out, but I just want to make sure it all adds up and is well presented.
My explanation is this:
The bottle opener uses the top of the bottle as a fulcrum so that when the handle is pulled up, pressure is applied to the cap stressing the metal, forcing it to bend and release the bottle.
Another part to the question is:
Explain why the bottle cap opener does not violate the law of conservation of energy.
My answer is:
When the cap is bent by the opener a small amount of heat is produced.
Are my answers correct and complete?
