Charle's Law - With constant pressure, temperature and volume are directly related
Ex. Pop can lab, when the can quickly went from hot to cold it imploded thus decreasing the volume
Boyle's Law - With constant temperature, pressure and volume are inversly related
Ex. Fog Cannon, when the shower curtain was hit it decreased the vume and increased pressure thus shooting the fog out
Gay Lusaac's Law - With a constant volume, pressure and temperature are directly related
Ex. Flask and Balloon, when the flask with water in it was heated up the balloon around the neck inflated and when it was put into ice water it sank in the flask because the molecules were trying to go from a place of high pressure to a place of low pressure and they brought the balloon with.

When I was a kid and i snowed outside I would go out and ride my inflatable tube down my hill in my backyard. After awhile the tube would "lose air". What was actually happening was since it was cold out the molecules in the tube would condense and the pressure would decrease. This also can happen to sports balls and tires a lot during the winter. This in an example of Gay Lusaac's Law.
Real Life Example #2
One day at lunch I was bored and began to twist a ketchup packet. Good idea right? Not really. after a few minutes of twisting it exloded out of the top and shot out a good 15 feet. This is an example of Boyle's law. When I was twisting the packet i was decreasing the volume inside of it and by decreasing the volume I was increasing the pressure. After so long that pressure had to be released and so it shot out of the packet.
Real Life Example #3
Once when I was younger I was with some friends, one of my friends suggested putting a marshmallow in a microwave. Another good idea. After a few seconds the marshmallow got huge. I quickly turned off the microwave to avoid a massive mess. This is an example to Charle's law, when heat was applied to the marshmallow it got larger and it's volume increased.
Good use of examples, and i agree with all of them
ReplyDeleteGreat job with the examples. I agree with it all, maybe give a reason for the temperature change.
ReplyDeletethe bottle and bike pump example was a good one. two thumbs up
ReplyDeleteI agree with your blogs but you need to explain it a little more
ReplyDeleteGood job on describing the labs but your should explain the laws some more.
ReplyDeleteok in case you can't see them there are links to youtube videos right underneath real life examples 2 and 3
ReplyDeleteGood job, you explained it nicely and I agree with almost all of your examples. I'm not positive, but I think for your first example if something implodes or explodes doesn't that mean there's a change in pressure, not volume?
