Is pressure in a balloon less than atmospheric pressure?
No, the pressure of the balloon is more than the atmospheric pressure because the gasses in the balloon are compressed by the stretched material.
What if a balloon is heated what happens to the volume of the air in the balloon if the pressure is constant?
For a balloon that is sealed and not full the volume of air inside the balloon will increase as it is heated. This is not however how hot air balloons work. A hot air balloon is essentially a fixed volume when it is inflated. If the air inside the balloon is heated the air inside becomes less dense so some of the air exits the balloon via the mouth of the balloon. As the air inside the balloon cools it becomes more dense so some air is ingested via the mouth of the balloon to keep it full. With each heating and cooling cycle, the pressure inside the balloon remains constant, the volume of the balloon remains constant but there is this movement of air out of and back into the balloon.

How does density volume and mass makes the hot air balloon to work?
Because hot air rises and cold air sinks. So when they heat the air in the balloon it becomes less dense or less heavy and that makes it rise ad the volume becomes more. Because hot air rises and cold air sinks. So when they heat the air in the balloon it becomes less dense or less heavy and that makes it rise and the volume becomes more.
Why does a sealed gas balloon expand when it is brought from ground level to the top of a mountain?
the air is less dense at altitude, therefore it exerts less pressure. the gas in a sealed balloon will exert the same pressure regardless of it's altitude, so, with less outside pressure to overcome, the balloon will expand.
How would you demonstrate the presence of atmospheric pressure?
Suck the air out of a container and watch it being crushed. Look at a balloon. Its round shape tells you that the pressure (atmospheric) from outside acts equally from all directions. Now take that balloon up a mountain and watch the balloon get bigger. There is less atmospheric pressure acting on the outside of the balloon the higher you go so the pressure inside the balloon makes the balloon bigger.

Why does helium balloons pop in the hot sun and what pressure is acting on it?
When heat is exposed to the helium balloon it becomes to be even less dense and the molecules begin to expand and eventually the balloon will pop.

When air pressure becomes lower as water molecules are added to the air what happens?
have less weight
What happens to pressure in water as you gets you gets shallower?
It decreases. There becomes less water to squeeze your body essentially, which is the premise of pressure.
When you heat the air inside a hot air balloon, it rises. Why does this occur?
D: The hot air inside the balloon becomes less dense than the air outside the balloon.
Why do weather balloons pop at certain altitudes?
As it rises up it goes into a region of lower pressure (pressure decreases in altitude) ans as it enters this region the gases in the balloon expand due to a thermodynamic relationship. Pressure and volume of the gas are related. PV= nRT (rearranged to P= nRT/V). So as it goes up in altitude the pressure goes down thus making the volume increase causing it to pop.
What happens to the volume of air in the syringe?
A syringe is similar to a balloon in effect on pressure. The more air you insert, the less space for fluid. The more pressure exerted on it, the less volume of air and the more the liquid would fill up the space.

As air becomes warmer it becomes less?
As air becomes warmer it becomes less dense (as long as the pressure remains constant)
How do convection currents make a hot air balloon to rise?
because the air becomes less dense and spreads out so becomes hotter and hot air rise so the balloon does.
