Air molecules collide into the balloon
with the same energy inside and outside the balloon. When the bottle is heated, the air molecules inside start moving faster. These molecules now collide into the balloon with more energy resulting in increased pressure. The increased pressure causes the balloon to expand.
What happened to the balloon in the hot water in the cold water?
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.
Why does balloon explode when heated?
When an air-filled balloon is placed in a flame, it bursts. Air is a relatively poor conductor of heat away from the thin layer of rubber. As a result, the
rubber overheats and the physical bonds holding the rubber polymers together are broken
.
What happens to the balloon when you heat and or cool it?
When cooled by liquid nitrogen,
the balloon shrinks
(not as much as the air-filled balloon) and it sinks down on the table. When heating up, the balloon slowly rises and flies up in the air again. Explanation 1: The volume of the balloon decreases by the low temperature, because the gas inside is cooled down.
Can a lighter pop a balloon?
Hold the lighter under the balloon with the air in it and see what happens.
Be careful as it should pop
! Light the lighter under the balloon with some water in it, be careful to hold the lighter under the part of the balloon where the water is. The balloon won't pop!
Why fireproof balloon is possible?
The flame heats whatever is placed in it
. It heats the rubber of both balloons. The rubber of the balloon without water becomes so hot, that it becomes too weak to resist the pressure of the air inside the balloon. … When water inside the balloon is placed in the flame, the water absorbs most of the heat from the flame.
Why does the balloon shrink in cold water?
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.
Does warm water increase blood flow?
Heat warms your body and helps blood flow throughout your body
. Better circulation may lower blood pressure and reduce risk of heart disease. Having a cup or two of hot water is an easy way to get your blood flowing.
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 happens to helium balloon when it is left in a cold room?
If you've ever left a helium-filled balloon in a cold room or vehicle, you probably came
back to a shriveled-up piece of latex
. … Temperature affects the density of gases such as helium, which is why helium-filled balloons appear to deflate in cold temperatures.
What is the relationship between volume and temperature?
These examples of the effect of temperature on the volume of a given amount of a confined gas at constant pressure are true in general: The
volume increases as the temperature increases, and decreases as the temperature decreases
.
What happens if you hold a lighter to a balloon?
When a balloon filled with air is held over a flame,
the balloon melts a little bit
. This means there is now a weak point in the balloon. The air inside the balloon pushes really hard on the melted part and makes the weakness get bigger, so the balloon pops.
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.
How do you make a balloon that doesn't pop?
- Scatter a handful of drawing pins evenly over a flat surface, all pointing upwards.
- Push an inflated balloon down onto the bed of pins.
- Be amazed as it doesn't pop!
Can balloons withstand heat?
You can use
Qualatex balloons during a warm day
. If you have options other than latex balloons, you can go for it because latex balloons start disintegrating after few days of exposure to warm weather. Do not inflate the balloon to 100%. Leave some space so that it can absorb the excess of heat due to warm weather.
Can you burn a water balloon?
The
water filled balloon does not burst
because the rubber obviously does not reach a temperature sufficient for it to melt or burn. … With air inside the balloon, this heat is not readily dissipated away from the spot touching the flame. As a result, the balloon partially melts or burns, then quickly bursts.
