Because when the particles move faster then you see it expanding.
because the rubber and the air expand .
With same mass, balloon get bigger with air than water because air is much lighter than water. With same standard volume, balloon get bigger with water than air because air is compressible and it will shrink down little bit from the pressure exerted by balloon wall.
By blowing up a balloon. if you show the kid the balloon when its not blown up then they'll see that it gets bigger when its full of air. If they don't believe that theres air inside then pop it and there will be nothing.
Yes, a balloon full of air will weigh more than an empty balloon because the air inside adds mass to the overall weight.
When you heat up a balloon in the oven, the air inside the balloon expands because the molecules have more energy, causing the balloon to inflate. If the temperature gets too high, the balloon may burst due to the increased pressure from the expanding air inside. It is not recommended to heat up a balloon in the oven as it can be dangerous.
A balloon gets bigger when it is filled with air or gas because the molecules of air or gas inside the balloon move around and take up more space, causing the balloon to expand. The pressure from the air or gas inside the balloon pushes against the walls of the balloon, causing it to stretch and increase in size.
its gotten bigger
Yes, an empty balloon weighs less than a balloon filled with air because the air adds to the overall weight of the balloon.
A full balloon contains more gas than an empty balloon (even an empty balloon contains a little air). Therefore a full balloon is heavier than an empty balloon (assuming the balloons are the same weight to begin with). However, if filled with a lighter-than-air gas, such as helium, the full balloon will defy gravity due to its increased buoyancy. The only other difference is that the skin of a full balloon will be stretched and will therefore be much thinner than the skin of an empty balloon. This stretching increases the pressure upon the gas contained therein, therefore the gas is compressed inside the balloon.
Decrease
Do you think 1 is bigger than 2
The balloon would expand and potentially burst if it's exposed to the rapid change in temperature from the fridge to the oven. The air molecules inside the balloon would heat up and increase in pressure, causing the balloon to inflate and possibly rupture.
