If you squeezed a balloon and made it smaller would the density in the air would become greater?
Yes. When you squeeze the balloon, you cause the volume to decrease. Since density is determined by dividing mass by volume, a decrease in volume will cause an increase in denisty.
Volume and pressure are held constant why does the hot air balloon rise and fall?
Although volume and pressure are held constant, some of the gas escapes from the bottom of the balloon, thus decreasing the mass of the gas in the balloon. If mass is decreased, then density is also decreased because density=mass/volume. Such a decrease in density of the balloon causes it rise.
What causes the buoyancy to increase or decrease?
Buoyancy force come from difference in density of the object and the surrounding. Buoyancy of the ship can change from the pay load inside its' space. More load per space reduce the buoyancy. For Balloon, buoyancy is change by increase temperature of gas inside to balloon since increase in temperature would cause gas to expand and had lesser density in its' cavity. In general, buoyancy increase or decrease by changing of density of the object or the surrounding medium.
Why does a heilum balloon float and not a oxyegen balloon?
because helium has less density
What property will decrease if temperature increases?
Density will usually decrease in this case.

What is the density of balloon?
Density of any balloon depends on the material of the balloon and how much the balloon is filled.

What would happen if a hot air balloon was sealed?
It needs to be open at the bottom to get heat from the burners into the balloon to warm up the air and decrease its density. If you sealed it off, eventually heat exchange through the fabric of the balloon would could the air off enough that the balloon would no longer be bouyant and it would lose altitute.
When a submarine pumps water out of its floating tanks its density decrease and it floats why does its density decrease?
Density = mass / volume. If the mass decreases, the density decreases.
Why does water's density decrease after potassium chloride salt is added?
The water density doesn't decrease.
Why does a heilum balloon float and not a oxyegen balloon?
because helium has less density
What property will decrease if temperature increases?
Density will usually decrease in this case.
What would you expect to happen to a balloon filled with air if it was put into a?
the balloon's volume would decrease!!!
When a balloon full of air is cooled its volume will do what?
Decrease
When a balloon is filled with air is heated does the density of the air in the balloon stay the same?
No it decreases
