What will happen to a balloon filled with air if it is placed above a candle flame and why?

The reason a balloon filled with air pops when you put it over a flame is because the rubber of the balloon gets very hot and weak and then breaks. Water has a very high heat capacity, much higher than air, so it will keep the balloon from bursting.

Why does the balloon with air pop but the water balloon does not what might be happening to the particles in the 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.

What will happen if a balloon is filled with air and then released?

Question 88. a) If a balloon filled with air and its mouth untied/ is released with its mouth in the downward direction, it moves upwards. This is the equal and opposite reaction in the downward direction as the air pushes the balloon upwards.

When I hold the balloon over the flame for a few seconds will it pop?

Hold the inflated balloon right above the flame. In just a few seconds, there will be a bang, and you will have a popped balloon in your hands.

What happens when you hold a balloon over a candle?

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.

When the balloon with just air absorbs the energy transferred to it from the candle what happens to the molecules of the balloon?

When the air-filled balloon comes near the flame of the burning candle, the rubber becomes hot. The air inside expands due to heating, and the balloon bursts.

How does the lighted candle affect the balloon containing water?

If you turn the balloon so that the candle flame is close to the side of the water balloon, the balloon will pop because the water is not conducting the heat away from the surface of the balloon. At least the water will help put out the fire! The soot on the bottom of the balloon is actually carbon.

What happens when an air filled balloon is left with its mouth downwards and allow the air to escape?

When the air filled balloon is left with its mouth downwards and allowed air to escape which is an action, the air exerts the upward force on the balloon which is a reaction. So, due to the reaction force balloon moves in the upward direction.

What happens when a balloon is filled with warm air?

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.

Why does a balloon expand when heated?

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 happens to balloons when heated?

If a balloon is heated up, the gas inside will expand, causing the circumference of the balloon to increase. Similarly, if the balloon is cooled down, the gas inside contracts, and causes the balloon to shrink.

What did you learn from the demonstration of the balloon and the candle?

Why does a balloon pop when you light it on fire?

Question Date: 2007-09-14. Answer 1: The reason a balloon filled with air pops when you put it over a flame is because the rubber of the balloon gets very hot and weak and then breaks. When you fill a balloon with water instead of air, the water absorbs most of the heat, so the rubber doesn’t get very hot.

Why does a balloon pop when it gets wet?

The skin (plastic) of the balloon is very thin, so it gets cooled by the water inside. If you held it over the fire long enough, eventually the water would reach a temperature that was too high for the plastic to survive, and then it would pop.

How do you pop a balloon with a candle?

Hold the water-filled balloon at the top while you slowly lower it over the candle and watch as people start to run. Everyone knows that it’s going to pop, but for some strange reason it doesn’t. If you’re very brave, you can actually allow the flame to touch the bottom of the balloon, but it still doesn’t pop.

What happens if you light a balloon with a candle?

But watch out! If you turn the balloon so that the candle flame is close to the side of the water balloon, the balloon will pop because the water is not conducting the heat away from the surface of the balloon. At least the water will help put out the fire!
