Why does a balloon inflated in hot water and deflate in cold water? In hot water, the Balloon inflated because of hot air molecules, and in cold water,
the Balloon deflated because of cold air molecules
. The hot air molecules are less dense in weight and tend to rise and occupy more space.
What happened to the balloon when cooled?
By the low temperature the pressure of the gas inside the balloon tends to decrease. … When the balloon is cooled,
the volume of the balloon is greater
, resulting in a greater average density of the balloon and helium. This makes the balloon come down.
Why do balloons shrink in cold water?
When the temperature drops,
helium becomes denser
. Its molecules lose energy, slow down and move closer together to conserve heat. This decreases the volume inside the balloon. Because the helium molecules are moving closer together, rather than outward toward the shell of the balloon, the balloon shrivels and shrinks.
Why does hot water inflate balloons?
Explanation: The
hot water causes the air inside the bottle and balloon to also heat up
. The faster moving particles inside the bottle start to move faster and faster and soon they expand to fill the balloon.
Will a balloon shrink in cold water?
The expanding gas blows up the balloon. When you put the bottle into cold water, the air cools down again. Cool air hasn't got as much energy, so it shrinks – and
the balloon shrinks with it
.
Does Hairspray make balloons last longer?
HAIR SPRAY Hair spray on the outside of the balloon will make it last a long time but don't touch it or it shrivels.
Hairspray actually helps keep the air in longer by sealing the balloon
. … Keeps your balloons bright ten times longer.
Why does an inflated balloon shrink when kept in a refrigerator?
Answer: A balloon shrinks inside a fridge
because of the way gases behave
. If the pressures remain the same on a fixed mass of gas, a drop in temperature will reduce the volume of the gas. The gas molecules get closer together and the density increases.
What happens to a balloon when pressure decreases?
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. If you warm air it will expand and density will decrease until the pressure inside and outside the parcel are equal.
Which weighs more a balloon filled with air or without it?
Weight of a balloon full of air: Still not much, but more than
an empty balloon
. Scales say “2”. So since a balloon full of air weighs more than the empty balloon – voila: Air has weight!
What do you feel as you press the balloon?
You probably feel the
air
pressing against the wall of the balloon with even greater force. … By squeezing the balloon, you reduce the space the gas particles can occupy. As the particles are pushed a bit closer together, they collide with more, so the pressure from the moving gas particles increases.
What happens if you inflate the balloon more?
When you inflate a balloon, you're actually putting gases, in this case mostly helium, into an elastic container. As you add more gas, the pressure inside the balloon increases, and in response,
the balloon expands
… … As you go higher into the atmosphere, the air becomes thinner, and the atmospheric pressure drops.
Why does a balloon inflate in hot water and deflate in cold water?
When the bottle is removed from the hot water, the balloon will stay inflated. This is because
the air molecules in the bottle are still hot
. … This will cause the balloon to deflate. When the bottle is placed into the pan of ice-cold water, the cold water causes the air inside the bottle to cool down.
What will happen when inflated balloon is kept in ice cold water?
When an inflated balloon is placed in cold water,
it shrinks
. This happens because the air inside the balloon occupies a smaller volume when the temperature is decreased, thus causing the walls of the balloon to collapse. … The temperature of air dictates the kinetic energy of the molecules.
Does temperature affect the size of a 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 the balloon when you squeeze the bottle?
When you punch a hole in a bottle,
the air molecules in the bottle have an exit
. They are pushed out as a balloon fills the space inside, resulting in room for the balloon to inflate. If the hole in the bottle is then plugged, the balloon stays inflated even when the mouth is removed.
What will make balloons last longer?
- Keep the latex balloons away from heat. Keeping them in cooler temperatures will prolong the life of the latex balloon. …
- Use a 60/40 inflater to inflate your latex balloons. …
- Spray hi-float into your balloon before using a 60/40 inflater. …
- Keep the balloon tied tightly.
