Do objects get heavier or lighter when heated?
Heating things up causes them to expand. As a result, a hot air balloon floats because the envelope containing the air (the balloon) has less air in it then the air outside the balloon at a lower temperature. This might be what you're thinking about.
Is moist air heavier or lighter than dry air?
Moist air is heavier than dry air, because of the water.
Is natural gas lighter or heavier than air?
Natural gas is lighter than air and rises.
How do you deflate a balloon by using a lighter?
The heat from the lighter, when placed on the surface of the stretched surface of the balloon,would melt the plastic of the balloon and allow the air inside the balloon to escape, so deflating the balloon.
Why does an argon balloon sink?

Is a helium balloon heavier than air filled balloon?

Does air pressure tell you how heavy air is?
Yes because when when you put a balloon in the air the balloon will tell you if its heavier or lighter.
List several types of lighter than and heavier than air vehicles?

Hydrogen or helium are used. As they are lighter than air that's why they float in air when filled in a balloon. Also, sometimes oxygen and carbon dioxide from your lungs, if you blew the balloon up with your mouth.
What gas is in a hot air balloon?

How does air make a balloon fly?

Do you make a balloon lighter when you blow it up?
If you blow it up with your mouth you make it heavier. You breathe out air containing a higher proportion of carbon dioxide than the air you breathe in. Carbon dioxide is a relatively heavy gas (nearly three times as dense as air) and so this increased amount of gas, plus the rest of the air in the balloon, will make the balloon heavier.
