This seems nuts - How can something create 3x more mass and give off significant energy in the process?

For instance, I have a fire going right now. If I put a 5# log on it will give of heat and light (weightess), it will give off ashes (perhaps 1% of prior weight) and it will give off smoke which goes up my chimney (how the hell much can that weigh?). So how does gas which is a refined substance triple its weight?

First, a gallon of gasoline does not weight 8 pounds, more like about 6 pounds. But, when it is burned it combines with oxygen in the air to produce carbon dioxide and water. Each pound of carbon produces about four pounds of carbon dioxide. Each pound of hydrogen produces about nine pounds of water.

Gasoline is approximately C8H10, so that six pound gallon contains about 5.4 pounds of carbon and this will yield about 20 lbs of CO2. Assuming the CO2 is considered a pollutant, then Mr. Gore's statement is more or less correct. Of course, if you don't consider it a pollutant, then not so much.

To make 44 pounds of CO2 you mix 12 pounds of carbon with 32 pounds of oxygen. The oxygen weighs almost 3 times as much as the carbon.

The change in weight associated with giving off energy is very very tiny. In the example above far less than a millionth of an ounce. A little mass is equivalent to a very large amount of energy. Energy =mass times c (velocity of light, a big number) squared.

When you burn something, like gasoline, you combine it with Oxygen. In the case of carbon, which has an atomic weight of 6, it gets combined with 2 atoms of Oxygen, each having an atomic weight of 8, so if there are 6 pounds of carbon, it becomes 22 pounds of carbon dioxide. (6 plus 16). The same happens for the hydrogen in the gassoline which as an atomic weight of 1. Each pound of hydrogen burned becomes 17 pounds of water...but I double Al counts water as a pollutant.

because your forgeting on of the ingredents used...

oxygen

oxygen weighs something.

i have an example of this...

you have a pound of Iron, and let it completely turn to rust. that rust will weigh more than a pound because oxygen is not combined with the iron atoms and that weight is now added to it.

Gore claimed he invented the internet also. Just another Liberal democrap full of S.
