How much helium is in a balloon that contains 0.54 grams of gas?
0.54 grams 1 mol = mass / Mr = mass / 4 (Helium's atomic weight is 4, it is a monoatomic gas) 1 mol = 0.54 / 4 = 0.00135 # of molecules of helium in the balloon = 0.00135 * 6.02 * 10^23
Why do balloons decrease in size after a while?
Why does a balloon go down after a few days?A balloon goes down after a few days because the helium can pass through the skin of a balloon which then reduces the size of the balloon and the balloon then slowly reaches the floor after loosing all its helium.If you need any more help visit www.wikipidia.comThey loose air somehow.
What will happen when a lid of a jar of helium is removed?
The bottle will just feel like a bottle full of air. In order for it to float like a balloon filled with helium, it would have to weigh less than air or you would need to fill the bottle to well over its capacity. 1 cubic meter of helium is required to lift 1kg.
How much helium is in a balloon that contains 0.54 grams of helium gas?
To calculate the amount of helium in the balloon, we need to convert the mass of helium gas to moles using the molar mass of helium. The molar mass of helium is 4 g/mol. So, 0.54 grams of helium is equal to 0.54/4 = 0.135 moles of helium. Finally, we can use Avogadro's principle to convert moles to the number of helium atoms present in the balloon.
What happens if helium balloons explode when you bust it?
Helium is an inert gas and will not explode. If however your balloon contains Hydrogen gas (which is not inert) instead of Helium gas, and it comes into contact with a flame, it will blow up in your face. (You should google the Hindenberg some time)
How do you make a balloon rise?
To make a balloon rise, you need to fill it with a gas that is lighter than the surrounding air, such as helium. Helium is less dense than air, so the balloon is able to float upwards due to the lifting force created by the difference in densities.
How do you make a balloon float again?
There are a few things you can do to help increase float time. First, be sure to tie a tight knot in the neck of the balloon. The balloons included in Balloon Time have extra-long necks for easier tying. If you are attaching ribbons to the balloons, be sure to tie the ribbon below the knot. For special occasions that require prolonged float time, you can also purchase and add ULTRA HI-FLOAT® product to your Balloon Time balloons.
Why doesnt a balloon float with your air?
A balloon does not float with your breath because the air you blow into it is denser than the surrounding air. To make a balloon float, you need to use a lighter gas, such as helium, which is less dense than the surrounding air and creates enough lift to keep the balloon suspended.
Where to find helium atoms to make a balloon float?
you can use alpha particles from a cyclotron to get helium nucleuses, then you need to get some electrons from a cathode ray tube, and then you need to put the electrons around the nucleus. This is the most tedious part.
Could you use helium to float an item into space?
No, air pressure increases as the balloon goes up, so the balloon will pop and fall to the ground. You can get high up in the atmosphere (but you need a LOT of helium and a balloon that can get VERY big) you will not reach "outer" space beyond the Earth's atmosphere.
Can you make a balloon fly without hot air or helium?
Yes, you can make a balloon fly using propellers or an electric motor to provide thrust. By attaching a propeller or motor to the balloon, you can create lift and propulsion to make it fly without the need for hot air or helium.
How much do you need to open a balloon shop?
a tank of helium and alot of those balloon thingy's
Can you fill helium balloons with normal air?
No it doesn't have helium. A hot air balloon derives it's lift from heated air, which is less dense and therefore lighter than normal air. A helium balloon derives it's lift from helium, a gas which at normal temperatures is less dense than normal air. So both fly 'lighter than air' but for different reasons.
What is the weight of water displaced by a massless balloon?
No real object is massless. Even a balloon has the mass of the balloon plus the mass of the entrained gas.But if the buoyancy of the entrained gas (hydrogen, helium) allows the balloon to float away, then it will displace no water. Even so, it still has mass.
Why does a balloon need hot air?
A balloon needs hot air to make it rise because hot air is less dense than cold air. When the air inside the balloon is heated, it becomes lighter and causes the balloon to lift off the ground and float in the air.
How many grams of helium must be added to a balloon containing 8g helium?
To inflate a balloon to a desired size, we need to know the volume and required lift. Typically a 9-inch helium-filled balloon can lift about 8g of weight. If you want to increase the lift, you can add more helium.
