If you blow it up with your mouth you make it heavier. You breathe out air containing a higher proportion of carbon dioxide than the air you breathe in. Carbon dioxide is a relatively heavy gas (nearly three times as dense as air) and so this increased amount of gas, plus the rest of the air in the balloon, will make the balloon heavier.
No
To blow up a big balloon without a pump, you can simply use your mouth to blow air into the balloon. Hold the neck of the balloon securely while blowing into it to inflate it. It may take a bit more effort and time compared to using a pump, but it is a simple and effective method.
A helium balloon floats up when released because helium is less dense than air. The helium inside the balloon is lighter than the surrounding air, causing it to create a buoyant force that pushes the balloon upward.
A helium balloon floats because helium gas is lighter than air. By filling a balloon with helium, the balloon also becomes lighter than air. The helium balloon floats for the same reason that objects float on water: objects less dense than water are pushed up by buoyant forces equal to the weight of water displaced by that object. What happens in water also happens in air, and the helium balloon is pushed upwards by a force equal to the weight of air it displaces.
Helium is lighter than air, so it makes the balloon float. If you let go of the balloon, it will float up into the atmosphere because of the difference in density between the helium inside the balloon and the air outside.
Helium gas is typically used to fill balloons to make them float or fly. Helium is lighter than air, so it causes the balloon to rise due to the difference in density between the helium gas inside the balloon and the surrounding air.
Helium is lighter than air, so it creates lift within the balloon causing it to float. When you blow up a balloon with human air (which mostly consists of nitrogen and oxygen), the balloon is heavier than the surrounding air and therefore falls to the ground.
because, helium is lighter than air so it flouts, if you blow it up yourself it will just fall down
Yes you have to but here is a tip: if you want the sturdiest balloon blow it up halfway and then insert pancakes before you blow it up anymore
When the gas particles hit the walls they blow up a balloon
Yes, if the air pressure in the bottle is higher than the pressure you are exerting to blow up the balloon, it can make it difficult or impossible to blow up the balloon inside the bottle. The higher air pressure in the bottle will resist the expansion of the balloon.

C4 and a detonator
To make air lighter, you can heat it up. Hot air is less dense than cold air, so it rises. When you heat the air inside a balloon, it becomes lighter than the surrounding air and causes the balloon to float upward.
No, girls cannot blow up a balloon with their nose. Blowing up a balloon requires forceful exhalation from the lungs, which is not possible through the nose.
The carbon dioxide gas in carbonation creates pressure inside the balloon, causing it to blow up. When the bottle of carbonated beverage is opened, the carbon dioxide gas rushes out and fills the balloon due to the pressure difference.
