If a balloon is placed on top of a fire, the heat will cause the air inside the balloon to expand rapidly, potentially causing the balloon to burst or pop. The rubber material of the balloon is not flame-resistant and could catch fire. It is not safe to place a balloon on top of a fire.
What else can I help you with?
Why doesn't the hot air escape out of the bottom of a hot air balloon?
Because hot air rises, the warmest air in the balloon is at the top of it. As time passes the balloonist has to fire the burners to maintain the temperature of the air in the balloon, and to prevent it being squeezed put by the higher pressure of the cold air surrounding the balloon.
Describe what happens when you inhale when you pull down on the bottom balloon in your model?
When you inhale and pull down on the bottom balloon, you create a decrease in pressure inside the model lung, causing the air from the top balloon to flow into the bottom balloon. This mimics the process of inhalation in the human respiratory system, where the diaphragm contracts to expand the lungs and draw air in.
What causes heat in air molecules in a hot air balloon to carry thermal energy to the top of the balloon?
As the air inside the balloon is heated, its molecules gain kinetic energy and move faster. The hotter air molecules are less dense and rise to the top of the balloon due to convection currents. This results in a temperature difference between the top and bottom of the balloon, allowing heat energy to transfer upwards.
How does an hot air balloon float?
If you have ever been inside a hot air balloon you see that they're gas cans inside the busket and that the 'pilot' lets them into the top of the ballon. Has he heats and the gas up it is given more energy and inturn his makes the particles move about more and this causes them to hit the casing up at the top. As he lets more gas into the casing the gas gets hitting each other more often and hitting the casing making it get larger. As the air inside the balloon is lighter than air as more is put inside the more upwards energy is put onto the balloon and the busket. (E.g. Weight.) Once the Upwards energy is greater than the weight the balloon lifts off and that's how it floats.
What are things you can do with water balloons?
throw them at people , have a water ballon battle, put them on top on doors so when they open they fall on the person who opened it, that's all I can think of
If you put a balloon that filled with water on the top of the fire what will happen?
die die
What will happen if a water balloon is placed on top of a lit candle?
The rubber of the balloon will melt and burn. Then once the rubber has a hole melted in it the water will fall out and put out the fire.
How does it feel if you put your feet on top of a balloon?
Rather than trying to describe it, why don't you get a balloon and try it?
If you put water yeast and sugar in a bottle and put a balloon over the top the balloon will inflate. Will it inflate if you do NOT put sugar in it If not will anything happen at all?
Yeast eats the sugar giving off CO2 which is a gas that will inflate the balloon. Added: But since carbon dioxide is heavier than air this balloon gas will never reach the 'top'
What should you make a drum out of?
A large or small can from vegetables or beans, And put A balloon on the top
What will happen if the warm water would affect the amount of carbon dioxide the yeast performs?
if you put a balloon on the top of the container the balloon will get bigger and bigger
What happens to a balloon if taken to a top of a mountain?
The balloon will expand as the air pressure decreases at higher altitudes. This is because the internal pressure of the balloon becomes greater than the external pressure. If the balloon is not released or deflated, it may pop.
How come when you put water in a balloon and you put it on top of lit candle it won't pop?
When you put water in a balloon and place it over a lit candle, the water in the balloon absorbs and distributes the heat from the flame, preventing the balloon from bursting. The water acts as a heat sink, keeping the balloon cool enough to withstand the heat from the candle without melting or bursting.
What two properties of a balloon makes it a good material to put over the top of the bottle?
flexible and stretchy
What happens when you put hot air into the balloon?
In hot air, particles are moving faster due to the increase in heat. This makes hot air lighter than cold air so the hot air will rise. When you put hot air into a balloon, the hot air will try and rise to the top. This allows the balloon to float in the air. Eventually the air will cool and sink back down which is why it's important to continuously pump hot air into the balloon to keep it up. Hope this helps! :)
What happens to the air in the top of the graduated cylinder when you press on the balloon?
The pressure increases and volume decreases. The air presses down.
Why doesn't the hot air escape out of the bottom of a hot air balloon?
Because hot air rises, the warmest air in the balloon is at the top of it. As time passes the balloonist has to fire the burners to maintain the temperature of the air in the balloon, and to prevent it being squeezed put by the higher pressure of the cold air surrounding the balloon.
