Why do balloons expand when rising?
As the balloon rises, the gas inside the balloon expands because the atmospheric pressure surrounding the balloon drops. The atmosphere is 100 to 200 times less dense at the float altitudes than on the ground. A balloon that is fully inflated on the ground will also have way too much lifting force.
What happens if you take a balloon up a mountain?
If the balloon is flexible, then it expands as it rises to altitudes with lower air pressure. If the temperature is constant, if pressure goes down, volume will go up (balloon expands). If T is constant, and the pressure goes up (say you hold the balloon underwater), then V will go down (balloon shrinks).
What would happen to the balloon if he took it to the top of a mountain where the pressure is much lower?
Routinely we make the pressure in the chamber equal to that at the top of Everest (approx. 29,028 ft). In a closed system: If the pressure is lowered, than the volume must increase. Therefore, when the pressure goes down, the balloons get larger and larger.
What will happen if inflated balloon is kept in a fridge?
The frozen balloon shrank because the average kinetic energy of the gas molecules in a balloon decreases when the temperature decreases. But if you let the frozenballoon warm up, you would find that it gets bigger again, as big as the balloonthat you left at room temperature the whole time.
Is pressure inside a balloon greater?
The gas pressure inside an inflated rubber balloon is always greater than the air pressure outside because the pressure inside balances the atmospheric pressure as well as the pressure resulting from the walls of the balloon.
What is the pressure inside a party balloon?
If it is filled with air, it is about 950 millibars plus or minus 75 millibars. Ok, that was fun. Seriously, it is only slightly higher than atmospheric pressure. That is 14.7 PSI more or less.
What happens if you put vinegar and baking soda in a balloon?
When baking soda and vinegar are mixed together, it creates a gas called carbon dioxide. The gas begins to expand in the bottle and starts to inflate the balloon. The more gas that is created, the larger the balloon will inflate.
