What might happen to a hot air balloon if the air inside is cooled down?
Only hot air rises, so if the hot air was cooled..... it would fall. Splat.
How are scientists able to make predictions?
You assume that things that happened repeatedly in a certain way in the past will happen the same way under the same conditions in the future. If you throw a ball up in the air 500 times and it comes down 500 times, you then predict that if you throw a piano into the air it will come down as well. If you throw a helium balloon up in the air for the first time, you might predict it will also come down. When it does not, this means the theory must be rejected or changed to explain what is different this time. If you have a hydrogen balloon and throw it into the air, you might predict that since your helium balloon did not come down and hydrogen is more similar to helium than it is to a piano, then the hydrogen balloon will keep going as well.
What would happen if a hot air balloon rose higher and higher in the atmosphere?
After you hit a certain altitude, the air would become so thin, it would starve the flame making the balloon rise of oxygen, the flame would go out, and the balloon would come plummeting back down to earth
What will happen to a gas balloon if you put it on the moon?
1) it will get as big as it can get. (no external pressure) 2) it will fall like a rock. (no air to buoy it up, no air resistance to slow it down)
How do you lower a hot air balloon?
There is a flap in the top of the balloon that you open to let the hot air out and the balloon gets lower. Or, you can just wait a little bit, the air cools down, and it goes down, all by itself!

What will happen if gas is cooled?
it'll slow down.
What happen when you pull down the balloon to the button of the lung model?
it will pop it
When does sublimation happen?
When unsaturated vapour is cooled down under freezing point
What would happen to a balloon if you brought it down to the bottom of the ocean?
It would probably fill up with water, and then you'd have a water balloon.
What would happen to the pressure if you cooled down the container?
The pressure inside the container would decrease.
What would happen to the earths plates if the mantle completely cooled down?
They'd stop moving.
What will happen to the convection currents in the mantle if Earth's interior eventually cooled down?
The convection currents will stop
What will happen when a salt solution has cooled down?
nothing unless you heated it and it starts to evaporate and cause the salt to stick to the side
Why an inflated balloon expand in warmwater?
Actually, it should decrease in size. The volume of a gas is directly proportional to the temperature of a gas (measured in Kelvin). Therefore if you inflate a balloon with your warm breath and then cool it down with cold water, the balloon will shrink, not increase in size.See the Related Questions for more information about the effect of temperature on gases.

What would happen if you fell down?
You might get hurt.
