because of the poor elasticity of the balloon
As the gas is pushed into the balloon the internal pressure increases, to reduce this pressure the rubbery material expands to increase the volume and ultimately reduce the pressure. Once the balloon is filled with CO2 and the knot is tied the balloon will probably sink this is because CO2 is more dense than air.
Imagine inhaling to blow in a balloon. You will take in air, hold it in your mouth and blow it into the balloon. Some of it will be the carbon dioxide you were exhaling but most of it will be the air you just breathed in. So, the gas inside the balloon will be a mixture, that is, air.
Hydrogen atoms are less dense than the air, therefore hydrogen balloon rises in air.
Determine the mass of an empty balloon. Then blow as much air as you can into the balloon and determine the mass again. The blown up balloon should be heavier and occupy more volume (is bigger). This shows that the air used to blow it up has mass and volume, and therefore is matter.
.45 mol
because it is stretched too far.... common sense i think.. no days its probably uncommon sense.
When you blow air into a balloon, the air pressure inside builds, thus causing the latex skin to expaand. Eventually, the latex won't be able to expand anymore, so it catastrophically fails. (AKA, it pops.)
the volume of air inside the balloon increases while the pressure of balloon decreases thus balloon inflates
becaz d air molecules require more space than required if u keep on blowing air into it
Blowing up a balloon.
a hot air balloon works when the hot air blowing from the bottom pushes up the balloon which lifts it up into the sky where it moves in the direction where the wind blows .
if you think about it, air molecules increase more and more. And the balloon has it flexibility. But the balloon can only stretch out a far distance. Henceforth, too much air molecules from you will make the balloon pop
force
Yes, It is a physical change because it's only losing air. when you put air in the balloon it's still a balloon, and when it loses air it's still a balloon. So it's a physical change since it didn't change in substance.
What they do is blast cold air into the "hot" air and it makes the air molecules slow down... Thus it makes the air balloon decrease back to earth.
Air fill the balloon and force it to expand but being a rubber base substance the balloon always in the state of pushing the air (that's why if you put a hole on a balloon it will "fly"). Air pushing is an action. Balloon pushing back is a reaction.
Instead of blowing normal air (your breath, a pump, etc.) into the balloon, you'd use helium to make it float.
