The air will expand, increasing the volume
The volume of the balloon decreases
It decreases. The colder air contracts, making the balloon shrink.
When an inflated balloon is exposed to cold air, provided pressure is constant, the volume will decrease. Bring the balloon back to a warmer spot, and the gas gains kinetic energy from the warm air, and the balloon will plump back up.
the volume of air inside the balloon increases while the pressure of balloon decreases thus balloon inflates
The volume of the balloon will increase as it rises in the air. This is because the atmospheric pressure decreases at higher altitudes.
volume decreases considering the pressure is constant
assuming the balloon is closed, the air pressure would double
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. P=VT Poop
if vigorous enough to create heat the balloon will expand.
Liquid nitrogen has a low temperature, and that obviously decreases the volume of the air inside the balloon. The balloon shrinks
The internal air would cool down and contract (lessen) the balloon's volume.
It stays the same
