At what pressure will a balloon pop?
One experiment shows that the balloon reaches a relatively constant pressure of 810 mmHg until it gets close to its maximum elasticity point and then increases to 820, 830 and finally 840 mmHg when it pops.
How do you calculate pressure in a balloon?
pv=niu*R*T ( eq. 1) . If you find the number of moles ( niu ) you’ll get the pressure ( since you can calculate , with a good approximation, the volume of the balloon using a water container and sinking it into this water, measuring the difference between the initial and the final levels of water etc. ).
What is the pressure inside inflated balloon?
There is not one pressure inside a balloon. Neither is there one pressure outside the balloon. The pressure inside a helium-filled balloon decreases with height (from bottom to top of balloon) slower than the pressure decreases over the same height in the air outside the balloon. That’s why there is a buoyancy force.
What causes a balloon to explode?
The rubber is stretched thin so that heat is quickly transferred into the balloon. 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 happens if a balloon pops in your mouth?
Inflated balloons should never be put in the mouth or too near to the face. When a balloon pops, the latex material from which it is made tears and shreds, which can not only hurt if it strikes someone’s skin, but it can cause injuries such as lacerations, damage to or loss of eyesight.
What happened as you press the balloon and release it?
The collision of these air particles with the walls generates a high-pressure environment inside the balloon relevant to the atmospheric pressure around it. This is why when a balloon is released; the high-pressure air flows out of the balloon to the low-pressure air surrounding it: ‘Winds blow from high to low.
What happens to the pressure of a gas in a small balloon when you inflate it?
When gas molecules bump into things, it creates pressure. Pressure is greater when gas molecules occupy a smaller space, because the greater crowding results in more collisions. In other words, decreasing the volume of a gas increases its pressure.
Can you press the balloon with you hands Why or why not?
1. can you press the balloon with your hands? why or why not? answer:_______________2.
How does heat affect a balloon?
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.
Why does a balloon inflate when air is blown into it?
Blowing up a balloon involves forcing additional air particles from your lungs into the balloon. These particles hit the inside walls of the balloon creating enough air pressure to force the rubber of the balloon to expand and the balloon to inflate.
What happens to the pressure when you squeeze a balloon?
If one end of the balloon is squeezed, making the volume smaller, the pressure inside increased, making the un-squeezed part of the balloon expand out. There is a limit to how much the air/gas can be compressed, however, because eventually the pressure becomes so great that it causes the balloon to break.
Why do balloons violate Boyle’s Law?
Boyle’s law states that volume of a gas is inversely proportional to the applied pressure. Whereas inflating balloon violates Boyle’s law because there is increase in volume with increasing pressure.
What eventually happens if you heat up the container too much or push down too much?
Heating increases pressure They hit the walls of their container harder and more often. This increases the pressure. Sometimes the pressure gets so great that the container bursts. This is why balloons and tyres burst if you blow them up too much.
What law is inflated balloon?
Volume and Temperature: Charles’s Law If we fill a balloon with air and seal it, the balloon contains a specific amount of air at atmospheric pressure, let’s say 1 atm.
What happens when you release your hand after squeezing the balloon?
When you released the blown balloon, the potential energy is converted into kinetic energy, which is energy in motion. The air came out with some force from the balloon’s mouth towards you.
Will a balloon deflate in the freezer?
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.
Can you control the size of the balloon How will you do it?
Since the amount of air in a balloon is fixed, if you change its temperature its volume must change, and so must its size. So yeah: if you heat up a balloon, its circumference will get bigger, and if you cool it down, it’ll get smaller. Hope those help!
What keeps a balloon from expanding?
Gas pressure is the pressure that results from collisions of gas particles with an object. Inside the balloon, the gas particles collide with the balloon’s inner walls. It is those collisions which keep the balloon inflated.
