∙ 12y agoFor 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.

Take a look at the relationship:
PV=nRT
R is a constant. n is the amount of gas, which would be held constant in a sealed balloon. So:
P1 V1 / T1 = P2 V2 / T2
1- before
2- after
This algebraic equation can help predict the outcome of other cases as well.
taking just the balloon first, it is a solid body(flexible), on heating it undergoes cubical expansion, so the first thng that happens is the container(balloon) expands so untill a particular expansion of it the volume of air inside increases(gases dont have a fixed volume) they occupy the area they have .

therefore, if T is decreased then V will decrease also

Do gases expand in heat?
Yes. If the temperature increases, the gas expands (assuming the pressure remains constant).
What happens to volume if pressure remains the same and temperature goes up?
Volume increases! If pressure is kept constant then temperature and volume are directly related to each other.(Charle's law). It states that:V1/T1 = V2/T2
What happens to gas pressure when temperature rises?
If the volume remains constant, the pressure will increase as the temperature increases. In an ideal gas (under normal conditions, gases have a behavior that's close to that of an ideal gas), the pressure is directly proportional to the temperature. Assuming, of course, that the temperature is measured in Kelvin.
According to Boyle's Law if the volume and temperature of a gas in a closed container remain constantwhat happens to the gas's pressure?
It goes up.
What statement best describe the isothermal process?
The temperature remains constant
What happens to the pressure of a gas if the volume increases?
It will increase? No it will decrease when the same amount of gas is held at constant temperature.
What happens when a gas is compressed keeping the temperature constant?
If pressure is held constant, volume and temperature are directly proportional. That is, as long as pressure is constant, if volume goes up so does temperature, if temperature goes down so does volume. This follows the model V1/T1=V2/T2, with V1 as initial volume, T1 as initial temperature, V2 as final volume, and T2 as final temperature.
What happens to the speed of a wave if the medium temperature and pressure do not changes?
remains constant
What happens to the speed of a wave of the medium temperature and pressure do not change?
remains constant
How is isothermal possible in a balloon?
Isothermal is where pressure and/or volume changes, but temperature remains constant. Pressure, Volume, and Temperature are related as: PV = nRT =NkT for an ideal gas. Here, we see that since a balloon's volume is allowed to change, its pressure remains relatively constant. Whenever there is a pressure change, it'll be offset by an equivalent change in volume, thus temperature is constant.
What happens to the pressure if the temperature in K is doubled?
The initial pressure is halved. Use Boyle's law that relates pressure & volume at a constant temperature. P1V1 = P2V2 In this case the V1(initial volume) is doubled so V2 = 2V1 P2 = P1V1/V2 = P1V1/2V1 P2 = (1/2)*P1
Which law says that the product of pressure and volume remains constant at a constant temperature?
This is the Boyle law (or Boyle-Mariotte law).
What is A sample of gas occupies 1.55L at STP What will the volume be if the pressure is increased to 50 ATM while the temperature remains constant?
A sample of gas occupies 1.55L at STP. What will the volume be if the pressure is increased to 50 atm while the temperature remains constant?
What happens to density if an objects volume remains constant but its volume is decreased?
If an object's volume remains constant but its volume is decreased,its density becomes ambiguous and mutually inconclusive.

How will volume of a balloon change if pressure remains constant but pressure increase?
The volume will increase in proportion to the increase in absolute temperature.
