How does heat cause a hot air balloon to rise?
When air inside the balloon is heated, it becomes less dense and lighter than the surrounding cooler air. This lighter air creates a buoyant force that causes the balloon to rise. As the air inside cools down, the balloon will begin to descend.
What gas makes a balloon rise into the air?
Helium. It is lighter than air and provides buoyancy, causing the balloon to rise.
Why does a balloon need hot air?
A balloon needs hot air to make it rise because hot air is less dense than cold air. When the air inside the balloon is heated, it becomes lighter and causes the balloon to lift off the ground and float in the air.
How do you make a balloon rise?
To make a balloon rise, you need to fill it with a gas that is lighter than the surrounding air, such as helium. Helium is less dense than air, so the balloon is able to float upwards due to the lifting force created by the difference in densities.
What gas do you use to make a balloon float?
Helium gas is commonly used to make balloons float because it is lighter than air and creates lift. The helium gas in the balloon is less dense than the surrounding air, causing the balloon to rise.

How does helium make a balloon rise when air doesn'?
Helium is lighter than air. So helium balloon rises in air.
What gas makes a balloon rise into the air?
Helium. It is lighter than air and provides buoyancy, causing the balloon to rise.
What makes a child's balloon rise?
Helium. The helium gas in the balloon is lighter than the air outside the balloon.
How do you make a balloon rise into the air?
To make a balloon rise in the air, one way is to fill it with a lighter-than-air gas, such as helium or hydrogen. The gas inside the balloon is less dense than the surrounding air, enabling it to float and rise. The amount of gas and the size of the balloon will determine how high it can rise.
Why does the balloon rise?
because it contains helium that is lighter than air
What chemicals from the periodic table make a hot air balloon rise?
There are many chemicals found in a hot air balloon to make it rise. The main elements/chemicals are Helium and Hydrogen.
Why does a balloon need hot air?
A balloon needs hot air to make it rise because hot air is less dense than cold air. When the air inside the balloon is heated, it becomes lighter and causes the balloon to lift off the ground and float in the air.
What happen when a balloon is filled with helium?
When a balloon is filled with helium, it becomes buoyant because helium is lighter than the surrounding air. This causes the balloon to rise and float. The helium gas inside the balloon also increases the pressure, which helps the balloon maintain its shape and stay inflated.
Why do certain gases allow a balloon to rise?
Because the gases filling the balloon are lighter than the surrounding air.
If you wanted to make a balloon float in the air which gas should you use to fill the balloon?
Helium gas is lighter than air and hence balloons filled with helium will float in air.
How do you make a balloon rise?
To make a balloon rise, you need to fill it with a gas that is lighter than the surrounding air, such as helium. Helium is less dense than air, so the balloon is able to float upwards due to the lifting force created by the difference in densities.
