First, stretch the balloon opening.
Then, blow into the opening until your desired size.
Last, tie a knot at the opening to keep the air from escaping.
Your done.
When you place a balloon in a freezer, the air inside the balloon cools down and contracts. This causes the balloon to shrink in size. If the balloon is made of a material that can withstand the cold temperature, it will return to its original size when it warms up.
The hot air inside the balloon expands, making the hot air balloon fly.
the process of diffusion
The process is called "charging by conduction." When you touch a charged balloon to the electroscope, electrons transfer from the balloon to the electroscope, causing the electroscope to become charged.
Hot temperatures can cause the air inside the balloon to expand, making the balloon rise. Cold temperatures can cause the air inside the balloon to contract, making the balloon descend. Changes in temperature can also affect the buoyancy and stability of the balloon during flight.
A balloon has a certain weight due to the material it's made of. When you blow air into the balloon, the weight of the air inside balances out the weight of the balloon material, making the total weight of the balloon and air the same as the original balloon.

Yes, the myth-busters proved it by making a 22k helium filled lead balloon.
The hot air inside the balloon expands, making the hot air balloon fly.
Air escapes a balloon when the pressure inside the balloon is greater than the pressure outside, causing the air to flow out through the opening of the balloon. This process continues until the pressure inside and outside the balloon equalize.
The main science forces involved in making a hot air balloon are buoyancy, which allows the balloon to float in the air, and convection, which heats the air inside the balloon to make it rise. Additionally, drag and gravity play roles in determining the balloon's movement and stability during flight.
It decreases. The colder air contracts, making the balloon shrink.
