What happens when a tropical martime air mass pushes up against a polar continental air mass?
it creates heavy storms
How do we know the presence of air?
There is measurable atmospheric pressure at the earth's surface. The pressure must be coming from something. Air offers resistance to movement independent of the effects of acceleration. It also supplies thrust and lift to aircraft; the movement of aircraft would be hard to explain without air.
How does a balloon pilot use density to control the altitude of a balloon?
the pilot heats the air stored in the balloon with a large flame the hotter it gets the higher it goes because the heat changes the density to make it go up or down if the pilot decreases the size of the flame the hot air lowers because the smaller flame has less heat giving it a higher volume, but the air stays the same thus making it lower
Where do balloons go when you let go of them?
They fly up and up until the air density outside the balloon matches the gas density inside the balloon. This can be very high. Then they float at that level until they pop, or the gas leaks out and they descend. The rubber material then becomes litter in someone's landscape, or in the sea. Fish, Dolphins and seabirds can be killed by eating balloon rubber.
Does a cubic meter of air have less mass higher up?
Yes. The density of the air (and thus mass per unit volume) deceases all the way to zero (in space) as the altitude increases.
Does a blown up balloon have more mass then the empty balloon?
No, the mass of a blown up balloon remains the same as the mass of the empty balloon. The only thing that changes is the distribution of air inside the balloon, which may affect its volume and density.
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.
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.
Why does a blown up balloon weigh more than a flat one?
Since air is matter, it does have mass. So adding its mass to the mass of the balloon would cause the balloon to have more mass. Weight is a measure of the pull of gravity on an object and an object with more mass is "pulled" more, so the balloon with air in it would indeed be heavier than a balloon without air.
How heavy is a blown up balloon?
A blown up balloon is weightless because the whole thing is just air and air has no weight
Why a balloon can be blown up?
A balloon can be blown up by expanding the air inside it. When you blow air into the balloon, the pressure increases, causing the rubber to stretch and the balloon to inflate. The elastic properties of the rubber allow it to expand and hold the air inside the balloon.
Does air in a balloon have no measurable mass?
No, air is matter and all matter takes up space therefore, having a mass. You can find it by subtracting the mass of the balloon from the total mass of the balloon and the air. (You will need a very accurate scale.)
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 is inside a blown-up balloon?
gas
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.
Is it possible to put a blown up balloon inside another blown up balloon?
Yes, it is possible to put a blown-up balloon inside another blown-up balloon. This is commonly known as a "balloon inside a balloon" or "balloon nesting." It creates a layered effect and can be a fun way to decorate or create unique balloon arrangements.
When a blown up balloon is released how does it show that momentum is conserved?
When a blown-up balloon is released, it moves forward due to the air rushing out, while the remaining air and balloon move in the opposite direction. This demonstrates momentum conservation as the total momentum of the system (balloon, air, and surrounding air) remains the same before and after the release, despite the internal movements.
