GED Practice Question: Money to Burn…
Yeah, I gave you another GED question. Actually, it’s really three GED questions. Remember the super science experiment about burning money? You soak a dollar bill (or a HUNDRED dollars if you’re feelin’ REAL BRAVE…I ain’t responsible if you try this at home!) in alcohol and water. Then you add heat (SIZZLE, SIZZLE). The alcohol burns, but the dollar and water don’t burn.
Here’s the GED Practice Question: If you did the experiment in a vacuum (no air!), what would happen?
Would the dollar bill burn?
GED Answer: Remember what you need to have to burn something? Heat, oxygen, and fuel. That’s cuz the oxygen combines like magic with the molecules in the fuel to make something else (like ashes and smoke and stuff). Poof! You gotta have oxygen, so you gotta have AIR. Vacuum = no air = no burning. The dollar bill would not burn!
Would the alcohol burn?
GED Answer: Same answer here. Yeah, alcohol burns easier than a dollar… but to make fire you GOTTA have oxygen (and fuel and heat). No oxygen = no burning. That’s why, if you’re in the kitchen makin’ sausages and the pan catches fire (NOT MY FAULT!!!), you can put the lid on the pan to put it out. The lid keeps the air out, and the fire goes out. See?
What would happen to the water?
GED Answer: Depends how much heat you put on it. If you heat the water up, it could dry up into steam. Or if there isn’t enough heat, the water will just stay there or get warm. Not too exciting.
The moral of the story: To make FIRE, you gotta have OXYGEN, and OXYGEN is in the AIR! More nifty GED science next week, Dudes! Hey, send me a comment, if there’s some part of science that’s confusin’ you an’ you wanna know more about it!
