What causes the volume of a balloon to decrease?

What causes the volume of a balloon to decrease?

Explanation 1: The volume of the balloon decreases by the low temperature, because the gas inside is cooled down. At room-temperature the helium balloon is lighter than air with the same volume of the air, which makes it go up. By the low temperature the pressure of the gas inside the balloon tends to decrease.

How does heat affect the volume of gas in a balloon?

Temperature is proportional to volume in a gas, so the higher the temperature for a given number of gas molecules in a balloon, the larger the volume of the balloon. Answer 6: The more heat a gas has, the more kinetic energy its particles have. That kinetic energy generally means how fast particles are moving.

What happens to the volume when you inflate a balloon?

About Boyles law: Imagine you are holding an inflated balloon. According to Boyle’s Law, the volume of a fixed amount of gas decreases as its pressure increases. If the volume increases, its pressure decreases.

Why does the pressure of a gas increase when the volume of a balloon decreases?

Boyle’s law Because the volume has decreased, the particles will collide more frequently with the walls of the container. Each time they collide with the walls they exert a force on them. More collisions mean more force, so the pressure will increase. When the volume decreases, the pressure increases.

Why does decreasing the air pressure causes a balloon to expand?

Answer 3: When a balloon goes up higher in the air, its size will increase. Since there’s less air in the upper atmosphere, there’s less stuff pushing back on the balloon, and hence the pressure is lower, which allows the balloon to expand.

What happens to a balloon when air pressure decreases?

The ideal gas law equation tells us that the pressure of the air in the balloon will increase. As the balloon volume decreases, pressure inside the balloon increases. It eventually is able to balance the outside air pressure. You end up with a balloon filled with cold high density air.

How might a decrease in temperature affect an inflated balloon?

The frozen balloon shrank because the average kinetic energy of the gas molecules in a balloon decreases when the temperature decreases. This makes the molecules move more slowly and have less frequent and weaker collisions with the inside wall of the balloon, which causes the balloon to shrink a little.

What happens to a balloon when pressure decreases?

When inflating a balloon using a helium tank the volume of the balloon increases because?

Gas particles exert pressure on the walls of the container in which the gas is filled. For example, when a balloon is inflated, the air inside it expands, thereby exerting pressure on the balloon walls. As a result, the size of the balloon increases.

When a balloon is inflated Where do you think the air pressure is highest inside or outside?

The gas pressure inside an inflated rubber balloon is always greater than the air pressure outside because the pressure inside balances the atmospheric pressure as well as the pressure resulting from the walls of the balloon.

What happens to a balloon when the pressure applied to it is decreased?

Therefore the pressure in the balloon is approximately equal to the outside pressure and lower pressure gives a larger volume of the balloon. If your balloon is made of very strong material than its volume would not change and the pressure would be the same as your prof states.

What causes a balloon to expand when inflated?

This causes the He gas to exert a greater pressure on the inside of the balloon. Since the pressure on the outside of the balloon is essentially the atmospheric pressure, which is constant, the balloon will expand until the pressure of the He on the inside is once again equal to the pressure of the air.

What happens when you change the temperature of a balloon?

Changing the temperature of a balloon has no effect on the mass of the He inside the balloon, but a decrease in temperature WOULD have an effect on the volume of the gas in the balloon according to CHARLES’ LAW (which states that volume is directly related to the temperature of the gas at constant pressure).

How does the amount of air in a balloon affect pressure?

In A The pressure produced by the air molecules inside a balloon will first depend on the number of air molecules, N, in the balloon. As you add more and more air to something like a bicycle tire, the pressure increases. If there weren’t any air molecules at all there wouldn’t be any pressure.

What happens to V when air molecules are removed from a balloon?

If you were to remove 20% of the air molecules, V would decrease to 20% of its original value and pressure would stay constant. Part C: Increasing the temperature of the gas in a balloon will cause the gas molecules to move more quickly. They’ll collide with the walls of the balloon more frequently and rebound with greater force.
