How do the particles move in a glass of milk?
As milk is a colloid,so particles must move in brownian motion(zig-zag motion)
Why do the dust particles move when a beam of sunlight enter the room?
The random motion of small particles in the air is called Brownian motion (named after the botanist Robert Brown). This motion is caused by the collisions of the particles with the molecules of the gases making up the air.
What do radioactive nuclides cause molecules in the air to do?
ionize! I missed this question on my test:(
Why Brownian motion can be seen in liquids and gases but why not solids?
Because the atoms or molecules in solids are not able to move randomly, they are held in an ordered structure.
What happens if alcohol is kept in air?
When liquid is exposed to air, it tends to evaporate. This happens because the molecules are in constant motion, and from time to time, a molecule achieves sufficient energy to overcome the atmospheric pressure above the liquid, and it escapes as a vapor.
Air pressure is caused by?
air pressure is caused by the constant motion of air molecules
Does air contains kinetic energy?
Since air is comprised of molecules that are in constant motion, the air would automatically have kinetic energy on the molecular level. On the macroscopic level, if the air is in motion (such as wind) then it would have kinetic energy by virtue of being mass in motion.
How molecules in the air cause air resistance?
How molecules in the air cause air resistance?
What keeps the air in constant motion?
Well, since the earth is moving, the air moves arounds the earth. So, the rotation of the earth makes air move in constant motion.
What is air motion rate?
Bulk air motion is called "wind speed". Motion of individual molecules in air is covered by temperature and the "kinetic theory of gases".
Air molecules speed up the movement of objects in motion?
The friction (with the air molecules) would slow it down.
What is the combination of horizontal motion with constant velocity and vertical motion with constant acceleration?
That combination is called "projectile motion". In the absence of air resistance, its shape is always a parabola.
Does air molecules speed up the movement of objects in motion?
yes
What causes dust particles to move with brownian motion?
It is the movement of small particles caused by the fact that air mollecules are moving at high speed and hit the particles. It was firs noticed in pollen by a guy called Brown (so the name). He thought the pollen was moving coz it was alive, so he boiled it, but it still moved.
How do molecules in air cause air resistance?
Molecules get in the way. When something passes through the air, it has to move molecules out of the way, and they are usually pushed aside.
What happenes when liquid is exposed to air?
When liquid is exposed to air, it tends to evaporate. This happens because the molecules are in constant motion, and from time to time, a molecule achieves sufficient energy to overcome the atmospheric pressure above the liquid, and it escapes as a vapor.
What element of air determines its temperature?
Air is made up of molecules that are always moving randomly, even when there's no wind. Temperature is a measure of the average amount of motion of molecules.
