Air takes up space because it is made of particles. Gravity pulls on these particles and keeps them near Earth. The density, or thickness, of air changes the farther away you get from Earth. The higher you go above Earth’s surface the less air there is until there is none left!Sep 28, 2015.
Does air take up space yes or no?
But, like solids and liquids, air is matter. It has weight (more than we might imagine), it takes up space, and it is composed of particles too small and too spread apart to see. Air, a mixture of gases, shares properties with water vapor, the gaseous form of water that is part of air.
What are some examples of air takes up space?
Take a balloon and blow it up (fill it with air, that is, don’t explode it.) As the air enters the balloon from your lungs, the air (which is a gas) takes up space in the balloon. The balloon expands because the air inside needs to take up more space.
How does air have mass and volume?
So, in order to prove that air is matter, we need to prove that air has mass and takes up space. Although air has mass, a small volume of air, such as the air in the balloons, doesn’t have too much. Air just isn’t very dense. We can show that the air in the balloon has mass by building a balance.
Does air shrink when heated?
The faster molecules move, the hotter the air. So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward.
Does water occupy space?
Yes water occupies space because you need to understand that water is liquid and so it will be considered a state of matter and we know that matter generally has mass and occupies space. Water need extra space to leave it for the other things so you can say that it occupy space.
What happens when air has weight?
Air is not just empty space—it has substance, or mass. Because air has mass, Earth’s gravity attracts it and gives it weight. Because it has weight, and the air molecules are constantly bumping into things, it exerts pressure.
Does air weigh anything experiment?
In the balloon balance experiment, we are blowing up balloons. When blow-up balloons, the air is entering inside them and making the balloons expand. So, this shows that the air occupies space which eventually proves that it has weight. The deflated balloon loses its weight.
Does air explain mass?
Yes, air does have mass and does take up physical space, so, yes, air is made of matter.
Can we see air?
Air is all around us, but we can’t see it. So what is air, exactly? It’s a mixture of different gases. The air in Earth’s atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen.
Does air have mass and weight?
It might not seem like it, but air has weight. Anything with mass has weight, and we know air has mass because (for example) we can feel it when the wind blows. The total weight of the atmosphere exerts a pressure of about 14.7 pounds per square inch at sea level.
Does air expand more than water?
Physical Properties of Air A given volume of air at 20°C (68°F) can hold twice the amount of water vapor than at 10°C (50°F). As the heated air rises, it expands, which is measured at the surface as low air pressure.
Is air affected by temperature?
Temperature, Sunlight, and Humidity. Air temperature affects the movement of air, and thus the movement of air pollution. The warmer, lighter air at the surface rises, and the cooler, heavier air in the upper troposphere sinks. This is known as convection and it moves pollutants from the ground to higher altitudes.
What happens when the air inside a hot air balloon is heated?
Science tell us that hot air rises, and as the air is heated inside the balloon it causes it to rise upwards (because it is lighter than the cooler air on the outside). When the pilot needs to bring the balloon down again, he simply reduces the temperature of the air inside the balloon causing it to slowly descend.
Does water occupy space why?
If you have a glass of water and pour it into another glass, it takes on the shape of the glass. If you spill the water, it will go everywhere, because it isn’t in a container. Except for water, most liquids have particles which take up more space than they do when they are in their solid state.
Do solids occupy space?
If something is in a solid state of matter, it has a definite shape and volume. The volume of an object is the amount of space it occupies. A block of wood placed on a table retains its shape and volume, therefore, it is an example of a solid. If a liquid is poured on that same table, there are very different results.
What has no definite shape?
solid: Has a definite shape and volume. gas: Has no definite shape or volume.
Who first proved that air has weight?
Galileo described a method of measuring the weight of the air in detail, but for reasons that are not clear his result was in error by a factor of about two. Torricelli surmised that the pressure of the air might be less on mountains, but the first demonstration of this was by Blaise Pascal.
What is the weight of air called?
Air Pressur This is called air pressure, and we experience it with a total weight of 14.7 pounds per square inch pushing down on us.
Does air have shape?
Air is a gas. Like all gases, air does not have its own shape. It takes the shape of the container it is in. The main gases are nitrogen and oxygen.
