When a balloon is sent up into the air, it rises due to the lighter-than-air gas inside it (usually helium or hydrogen) being less dense than the surrounding air. As it ascends, the air pressure decreases, causing the gas inside the balloon to expand and the balloon to increase in size. Eventually, the balloon will reach a point where the gas inside it is in equilibrium with the surrounding air pressure, and it will stop ascending.
What else can I help you with?
What happens if the air balloon burner was turned off?
The balloon will crash. The burner keeps it up.
What is an example of air expanding?
An example of air expanding is when you blow up a balloon. The air inside the balloon takes up more space as you blow more air into it, causing the balloon to inflate and expand.
Why did they call it the hot air balloon?
A hot air balloon is called an hot air balloon because, the inside is heated up to make it less dense, allowing it to rise. Meaning, your heating up the air inside the balloon, hence, the name: Hot air balloon.
What makes the hot air balloon go up and down?
A hot air balloon goes up when the air inside the balloon is heated, causing it to become less dense than the surrounding air. This creates lift. To descend, the air inside the balloon is allowed to cool, increasing its density, which causes the balloon to lower.
Where does air go in a balloon?
When you inflate a balloon, the air goes inside the balloon and fills it up. The air molecules push against the walls of the balloon, causing it to expand and take on its inflated shape.
What is a name for a device that is sent up into the air to measure information about the weather?
weather balloon
What happens if the air balloon burner was turned off?
The balloon will crash. The burner keeps it up.
What happens to the weight of the balloon when blown up?
When a balloon is blown up, its weight remains the same. The air inside the balloon has mass, but it is not the weight of the balloon itself that changes. The buoyant force of the surrounding air supports the weight of the balloon.
What happens to when heat is added to a balloon filled with air?
the Balloon starts to get starts to heat up and then it pops
What happens to the weigh to balloon when it is blown up and why?
When a balloon is blown up, it becomes lighter because the air inside the balloon is less dense than the surrounding air. This causes the balloon to float or rise upward, due to the principle of buoyancy.
What happens to the weight of the balloon when it is blown up?
When a balloon is blown up, its weight remains the same. The weight of the balloon is determined by the amount of air it contains and the material it is made of. Blowing up a balloon simply changes its volume, not its weight.
What happens to a balloon when you heat it up?
When you heat up a balloon, the air molecules inside the balloon gain energy and move faster, causing the air pressure to increase. This increased pressure stretches the walls of the balloon, making it expand. If the balloon is heated too much, it can burst due to the increased pressure.
What is the device that is sent up into the air to measure the weather?
A radiosonde (RAY dee oh sawned) is a device that is sent up on a weather balloon to study weather conditions aloft.
What happens if you heat up a balloon?
Heating up a balloon causes the air inside to expand, increasing the pressure. If the balloon cannot withstand the increased pressure, it may burst.
What happens when you heat up a balloon in the oven?
When you heat up a balloon in the oven, the air inside the balloon expands because the molecules have more energy, causing the balloon to inflate. If the temperature gets too high, the balloon may burst due to the increased pressure from the expanding air inside. It is not recommended to heat up a balloon in the oven as it can be dangerous.
When a balloon is blown up then it is let go air molecules rush out of the balloon and join the air molecules in the earth's atmosphere. What happens to the enthaply in the balloon?
When the air rushes out of the balloon, it releases heat energy, which results in a decrease in enthalpy within the balloon. This process is known as an exothermic reaction, where energy is released to the surroundings.
Which property of air does a empty balloon and a blown up balloon show?
An empty balloon and a blown-up balloon both demonstrate the property of elasticity in air. The empty balloon can expand when air is blown into it due to the elasticity of the air inside the balloon, and the blown-up balloon can return to its original shape when the air is released, also due to air's elasticity.
