you use a string, or something of that nature, tie it around the balloon, then measure the length of the string, the circumference. Uses the circumference to find the area/volume.
Use area and volume of a circle.

∙ 13y ago- You could submerge the balloon in water and measure the overflow. This would give a close answer but the pressure of the water may mean the measured volume is less than the actual volume.
- You could get the diameter of the balloon if it is spherical and calculate the volume of a sphere (V =4πr3/3).
- You can't use a gas law calculation as you do not know the number of moles of gas in the balloon. But air is a mixture of gases ~20% oxygen and 79% nitrogen. You could calculate approximately the number of moles from the weight of air in the balloon using the following formula. (Mass of filled balloon - mass of empty balloon) x 0.21/32 +(Mass of filled balloon - mass of empty balloon) x 0.79/28 ≈number of moles.
PV = nRT
Where
P = pressure (kPa)
V = volume (dm3)
n = number of moles
R = Ideal gas constant, 8.31
T = temperature in Kelvin

∙ 13y agoTake one typical balloon, and fill it up just the way you always fill them.
When it's full and you're ready to tie the end closed, don't do it. Instead,
take a big measuring cup, and pour the water back out of the balloon into
the measuring cup. See how much water you have in the measuring cup,
and you have the answer to your question.
If you want to be more scientific about it, do the same thing five times, and
write down the five different amounts it takes to fill five different balloons.
Add up the five numbers, and divide the result by 5. That gives you the
average amount of water it takes to fill each balloon, even if they don't
all take the same amount.

∙ 9y agoTo find the volume of an inflated balloon you use the formula for sphere volume. The formula is V equals 4/3 times pi times radius squared.

What will happen to an inflated balloon if it is put in a refrigerator?
it will shrink because the volume will decrease
What happens to the temperature and the volume of an inflated balloon if it is taken outside on a cold winter day?
The internal air would cool down and contract (lessen) the balloon's volume.
Inflated balloon that is taken from a heated roomto a cold outdoor?
The balloon will shrink when it goes outside. How much it shrinks will depend on the temperature difference. As temperature decreases the gas(ses) in the balloon decrease in volume causing the balloon to shrink.
What is inside the inflated balloon?
Helium goes into a balloon to make it float.
How do you make an experiment to show that air occupies space?
The easiest way to demonstrate the volume of air is with a balloon. When it is inflated, the air inside is occupying space. Deflate the balloon - it shrinks in the absence of air.
When an inflated balloon is exposed to cold air?
The volume of the balloon decreases
What will happen to an inflated balloon if it is put in a refrigerator?
it will shrink because the volume will decrease
What volume of helium in a balloon half a mm thick?
You will need to know the actual size of the balloon as the bigger its inflated the more gas volume required.
What occurs to the volume of an inflated balloon when exposed to cold air?
It decreases. The colder air contracts, making the balloon shrink.
What happens to the temperature and the volume of an inflated balloon if it is taken outside on a cold winter day?
The internal air would cool down and contract (lessen) the balloon's volume.
Partially inflated weather balloon has a volume of 1.56 x10 to the 3 power L?

A weather balloon is inflated to a volume of 2.2 x 103 L with 37.4 grams of?

Is there a PICC line with an inflated balloon for placement?
There is not a PICC line with an inflated balloon for placement.
What happens when an inflated balloon is exposed to cold air?
When an inflated balloon is exposed to cold air, provided pressure is constant, the volume will decrease. Bring the balloon back to a warmer spot, and the gas gains kinetic energy from the warm air, and the balloon will plump back up.
who inflated a balloon?

What is the difference in the height of the balloon after ten minutes and the height of the balloon after sixty minutes?
There is no difference at all if the balloon is not inflated or inflated with air.
What happens to the volume of his chest cavity when he inhales?
The volume of the chest cavity is reduced on exhalation. Imagine your lungs are balloons. Imagine the volume of a balloon full of air, compared to when it is not inflated. The balloon has a greater volume when it is inflated than when it is deflated - just like the lungs do!
