What happens to the volume of a balloon when it gets cold?

What happens to the volume of a balloon when it gets cold?

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.

What happens to the volume of a balloon when it gets hot?

As the temperature increases, the gas particles absorb more heat energy. They speed up and move farther away from one another. So the increase in temperature causes an increase in volume.

What happens to the volume of a balloon when it is taken outside?

The volume of the balloon will decrease outside because the gas particles move more slowly and exert less pressure. The air particles in the balloon take up less space.

What will happen if inflated balloon is kept in a fridge and why?

The balloon will shrink. The frozen balloon shrank because the average kinetic energy of the gas molecules in a balloon decreases when the temperature decreases.

What happens to the volume of a balloon when it is placed in the freezer which gas law applies?

Explanation: Charles’ law holds that for a given quantity of gas, V∝T . The colder the temperature, the smaller the volume. Thus the balloon will contract, as the gas gets colder.

What happened to the size of the balloon meaning its volume when the temperature decreases?

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 the volume of a gas inside a balloon if you keep on inflating it?

Robert Boyle, a chemist and physicist from the 17th century, discovered that the volume of gas, meaning how much space it occupies, is related to its pressure—and vice versa. He found that if you pressurize a gas, its volume contracts. If you decrease its pressure, its volume increases.

What will happen to the volume of a balloon if pressure is kept constant and the temperature is lowered?

If temperature is held constant, the equation is reduced to Boyle’s law. Therefore, if you decrease the pressure of a fixed amount of gas, its volume will increase. However, if you were to maintain a constant volume while decreasing pressure, the temperature would also have to decrease.

What happens to a balloon when the temperature goes up?

So…If the temperature is constant, if pressure goes down, volume will go up (balloon expands).If T is constant, and the pressure goes up (say you hold the balloon underwater), then V will go down (balloon shrinks).If the volume is constant (say, an aerosol can) and the temperature goes up, then P goes up.

What was the original volume of a balloon?

A balloon originally had a volume of 0.439 L at 44°C and a pressure of 729 torr. To what temperature must the balloon be cooled to reduce its volume to 378 mL if the pressure remained constant? Gas density can be calculated by dividing the mass of gas by its volume.

What is the external pressure of a balloon?

At sea level, the external atmospheric pressure of the air is equal to 14.7 lbs/in 2 or 1.0135 bar or 1 atm (those three values are all equal just like 1 yard is equal to 0.9144 meters). Since the balloon’s volume is not changing, we know that the outside pressure on the balloon is balanced by the air pressure of the air inside the balloon.

How is the volume of a gas related to the temperature?

This is an example of Charles’ law, sometimes called the temperature-volume law. It states that the volume of a gas is directly proportional to the Kelvin temperature, while pressure and amount are held constant. The equation is V 1 T 1 = V 2 T 2, where V is volume and T is temperature in Kelvins.
