The different molecules that make up the air in a room have on average the same kinetic energy how does the speed of the different air molecules depend on their masses?
If mixed together, molecules with various masses will move at different speeds related to their mass.
When air is heated it rises this is because?
The space between the molecules in the air mixture increases which decreases the density of the air. As the density decreases, the mass of warm air rises.
A brick has greater mass then a sponge why is the acceleration due to gravity the same for both objects?
acceleration downwards has nothing to do with mass...gravity is a constant accelerated pull (9.81 m/s^2)....acceleration = distance/time The reason why a feather hits the ground after a brick is because of air molecules...it is more difficult for air molecules to stop an object with more mass
Why is airpressure greater near the surface?
Air pressure is greater near the surface because air has mass, which means that the mass of the Earth causes the force of gravity to pull the air towards the surface. This causes the air molecules to compress, which increases air pressure. At the same time, the air molecules want to depressurize, because they are a gas, causing them to physically push on each other. This causes the air pressure closest to the surface to be highest, because the depth of the air above those closest to the surface is greatest. As altitude increases, air pressure decreases for the same reason - there is less mass pushing from above.
How molecules in the air cause air resistance?
How molecules in the air cause air resistance?
What is the mass of air of mesosphere?
a few molecules
Does air have mass because it is composed of atoms and molecules?
yes.
Are air is weightless?
Air has weight because it is made up of molecules of matter and all matter has weight and mass.
What gives wind mass?
Hello! Air molecules that float in our sky give wind its mass.
Why hot air mass generally rises?
Cold air masses have molecules that are densely packed and close together, unlike warm air.
Does a red balloon has more mass then green balloon?
Yes. Air is made up of tiny molecules and atoms (That can only be seen with the most powerfull microscope). The molecules and atoms are "matter". So air has matter anywhere it might be.
The different molecules that make up the air in a room have on average the same kinetic energy how does the speed of the different air molecules depend on their masses?
If mixed together, molecules with various masses will move at different speeds related to their mass.
Does air take up room?
Air does indeed take up room. Air molecules have a mass that takes up whatever room it is confined to.
When a warm air mass overtakes a cold air mass it form a?
Yes. Cold air masses have higher density, because the molecules are closer together. That makes them have higher pressure because there is more mass per unit volume pressing
Great masses of air molecules pushing down from adove?
It is AIR PRESSURE!!
When air is heated it rises this is because?
The space between the molecules in the air mixture increases which decreases the density of the air. As the density decreases, the mass of warm air rises.
What is heavier damp air or dry air?
Dry air is "heavier" than moist air, that is, it is denser. The water molecules in humid air do not fit in between "air" molecules (diatomic nitrogen and oxygen in a 79:21 ratio), they replace them, as per Avogardo's number of molecules in a mole of a gas. One molecule of diatomic nitrogen has a mass of 32 AMU and of diatomic oxygen, 28 AMU. A water molecule only has a mass of 16 AMU. Don't believe it? Think about it: a high pressure system is dry air and is higher pressure because it is a sinking air mass. It sinks because it is heavier.
