Probably the simplest way would be to fill a container having a known volume (say, a 5 gallon bucket) with water right to the top, weigh it, then push the balloon under the water. The water displaced by the balloon will spill out. (Your hand will displace water too, which screws things up, so use something like a stick to push the balloon all the way in.) Now take the balloon out of the water and weigh the bucket again. The difference between the earlier weight and the final weight is the weight of the water that the balloon displaced. The density of water is 1 gram per cubic centimeter (cc), so (to a very good approximation) the volume of air in your balloon in cc is the same as the weight of the displaced water in grams.
What else can I help you with?
How could you use an inflated ballon to show that decreasing the volume of a fixed mass of air increases its air pressure?
If you decrease the volume of a fixed mass of air inside a balloon by squeezing it, the molecules inside become more crowded, leading to an increase in air pressure. You can demonstrate this by inflating a balloon and then squeezing it - the balloon will become harder as the volume decreases, showing an increase in air pressure.
What are the three main parts to a balloon?
The three main parts to a ballon is the ballon itself, the gas inside it (air or helium), and the knot that keeps the gas inside.
Why will a balloon left inside a car on a hot summer day become larger?
the reason why a ballon left inside a car on a hot summer day become larger is because the air particles inside the ballon collise with the ballon walls more frequently. I guess......
Why is wind matter?
Wind is a mater because it takes up space. For example if I fill in a ballon with air the ballon takes up space. Also I can measure wind by putting the ballon on a scale
What are the giant balloons you can climb inside called?
If there is a basket underneath it is a hot-air ballon
What if you put a inflated balloon in the refigerator?
It would get smaller as the air inside the ballon contracted.
Jay takes a fully inflated ballon and put it n a freezer two hours later the ballon appears deflated. what is this?
The decrease in temperature caused the air molecules inside the balloon to condense, reducing the pressure and volume of the gas. This resulted in the balloon appearing deflated when removed from the freezer.
What happens if you put ballon in the hot water?
When you put a balloon in hot water, the air inside the balloon will heat up and expand, causing the balloon to inflate and possibly burst due to the pressure buildup. The heat causes the air molecules inside the balloon to move faster and spread out, increasing the volume of the air inside the balloon.
What happens to the volume of a hot-air balloon when the heater is turned off?
When the heater is turned off, the air inside the balloon cools down, causing it to contract and the volume of the balloon to decrease. This decrease in volume creates less lift, causing the balloon to descend.
Why balloon kept in sun burst after some time?
pressure x volume divided by temperature is a constant (Boyle's Law), or PV/T = constant. Since pressure does not change, as temperature increases so must the volume, so the balloon expands
Explain why an inflated balloon shrinks when placed inside the refrigerator?
The reduce of temperature when put into the fridge will cause the air particles inside the balloon to have less kinetic energy than before . Thus, the air pressure is lower and as the air particles hit the wall of the balloon less often, it will cause the balloon to shrink.
How do you get the density of a ball without knowing the radius or the volume?
Unless you can calculate or measure the volume, you cannot. And even if you could you would get the average density - of the material of the ball and the air inside.
