Heating a Balloon
Can you really use a candle to heat water in a balloon without popping it?

Water absorbs the heat fast

Water absorbs the heat fast sufficient to keep the rubberized through obtaining very hot sufficient to dissolve. You can do exactly the same thing using drinking water in the report cup. Water will keep the report cup through burning up. That is not utilize a Styrofoam cup. Foam is simply too thicker and it is an unhealthy director, therefore the cup receives very hot sufficient to dissolve prior to the drinking water within may digest the heat.

Water is a very very good

Water is a very very good conductor of heat, plus it includes a high specific warmth, meaning it could take in a lot of warmth energy. The water absorbs the warmth quickly enough to help keep the particular rubber from getting hot enough to be able to melt. That can be done the same thing together with water inside a document glass. The water helps to keep the particular document glass from burning. This does NOT work with a Styrofoam glass. The Styrofoam is too thick and is a poor conductor, so the glass becomes hot enough to be able to melt before the water inside can take in the warmth. toenail fungus

cool!

really cool!! I've always wandered, did you say "have a wonderfull week" or "have a wonder filled week"??

your biggest fan!!

coool

im going to do that at home =)

Heating a balloon activity

If the water absorbs the heat so the balloon doesn't melt. Would water be considered an insulator of heat or a conductor of heat. Does that hold true for water in a pan over the stove? I always assumed water was a conductor of heat, that is how it eventually boiled.

RE: Heating a balloon activity

Water is a very good conductor of heat, and it also has a high specific heat, which means that it can absorb quite a bit of heat energy. The water absorbs the heat fast enough to keep the rubber from getting hot enough to melt. You can do the same thing with water in a paper cup. The water keeps the paper cup from burning. This does NOT work with a Styrofoam cup. The Styrofoam is too thick and is a poor conductor, so the cup gets hot enough to melt before the water inside can absorb the heat.

We did this in class and the balloon did not pop

I suppose i depends how close

I suppose i depends how close the heat source is to the balloon.

Huh?

How is that possible. Wouldn't the balloon still pop and then the water will get on the flame and then the flame will go away still?

The water absorbs the heat

The water absorbs the heat fast enough that the balloon does not get hot enough to melt. That keeps the balloon from popping.

RE: Huh?

If the water boils for long, it will overinflate the balloon and pop it, but you can get to the point where it is starting to boil without popping.

Huh?

That doesn't make sense to me. If the water got to boiling, wouldn't the ballon pop?

These are short, science oriented videos that don't fit neatly into other categories. Many are just for fun, as I learn more about the world of video.
