When you blew a birthday balloon what gas will it be inside the balloon?
Imagine inhaling to blow in a balloon. You will take in air, hold it in your mouth and blow it into the balloon. Some of it will be the carbon dioxide you were exhaling but most of it will be the air you just breathed in. So, the gas inside the balloon will be a mixture, that is, air.
Why would heating a gas in the air balloon make the balloon rise?
By radiating energy, the heat excites air molecules to expand, within the confined space of the balloon's lower density and over all mass, causing the whole thing including the container to float.Hot air is lighter (less dense) than cool air, so it rises.Because the cool air is denser it occupies less volume. The cooler, denser air will slide down beneath the warm air mass, thus providing lift to the balloon.If you heat a gas such as air, it will expand - more volume for the same mass. This means it will be less dense - less kilograms per cubic meter for example. Being less dense than the surrounding air, it will tend to float - but of course, the upwards force must be enough to compensate the balloon's weight.Because hot air rises. Period. Nothing fancy. The air in the balloon would be hotter than the air around it, so it will rise.Hot air is less dense than colder air, therefore the hot air balloon will float on the cooler air surrounding it.
Why a balloon filled with hydrogen gas floats in air?
bcoz hydrogen gas is less denser than air and is exerts buoyant force on balloon
What happens when an inflated balloon is exposed to cold air?
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.
What happens when liquid nitrogen is poured on balloon?
Liquid nitrogen has a low temperature, and that obviously decreases the volume of the air inside the balloon. The balloon shrinks
Is inside a balloon a solid?
No, the inside is a gas (air).
What can you say about the gas inside a balloon?
The gas inside of a balloon is less dense than the air outside of it if the balloon floats. If the balloon does not float the density of the gas inside of it is equal to or more dense than that around it.
Why does the air change the shape and size of the balloon?
Because the air is coming inside the balloon.

What is inside an hot air balloon?
hot air or hot gas
What makes balloons go up?
One of two reasons, either the gas inside the balloon is lighter than the air around it, as would be the case if the balloon was filled with helium, or the gas inside the balloon is hotter than the air around it, as is the case with hot air balloons.
What type of gas is used in a hot air balloon?
A hot air balloon is normally powered with propane. Other than that, it is just ordinary air used inside the balloon.
Why would heating the gas in a hot air balloon make the balloon rise?
When the gas (air) in a hot air balloon is heated it becomes less dense. This makes the balloon more buoyant so it rises.Because heating the air inside the balloon makes it less dense than the air surrounding the outside of the balloon, so it will rise.
Does a air in a balloon?
A balloon floats in the air when the molecules inside the balloon are less dense. The gas inside a helium balloon is in essence "lighter" than the air around it, causing a buoyancy effect which makes the balloon float. This can also be seen in hot air balloons when the air molecules are heated by the propane torch and excited, thus creating a less dense environment inside of the balloon compared to outside of the balloon.

What happened when a balloon filled with air was squeezed and gently pressed?
The air inside the balloon is at a higher pressure than atmospheric pressure so the gas molecules inside the balloon are closer together on average than gas molecules outside the balloon. This means that the repulsive forces between the gas molecules inside the balloon are greater than the repulsive forces between the gas molecules outside it. When the balloon is opened, the gas molecules in the open end at the border between the higher pressure interior and lower pressure exterior will experience a greater repulsive force from the gas molecules inside the balloon than the molecules on the outside. This means that they experience a net force pushing them out of the balloon. As these gas molecules are pushed out by the gas inside the balloon, they push back on it with an equal and opposite force (due to Newton's 3rd Law of Motion). This equal and opposite reaction force causes the gas in the balloon to be pushed in the opposite direction to the escaping gas, which in turn pushes the balloon. As more and more gas escapes, the reaction force on the balloon continues to accelerate it, making it shoot off, until enough gas has escaped for the pressure inside the balloon to have dropped to the same level as the pressure outside the balloon.
What kind gas is used in hot air balloon?
No Gas Just hot air which is why it is called a hot air balloon. If you were wondering hot air is lighter than cold air which makes it rise so when it is trapped inside the balloon the whole thing will rise.
