Brownian movement, Brownian motion, or pedesis is the random movement of particles suspended in either a liquid or a gas. This is the movement that you see when sunlight is streaming through a window and you see the dust particles randomly moving. This movement helped to prove the existence of atoms and molecules. Many scientists, including Albert Einstein, used this motion to describe movements in the Stock Market, among other things!

How does sound travel from instruments to your ears?
Sound creates waves in a material- compression waves. These waves are transmitted through the atoms/molecules in the material to the receiver. The denser a material is, the more effectively sound may travel; this is because the sound waves are transmitted more easily through the tightly packed molecules.
What will vibration of air molecules produce?
Vibrating gasses, like air, produce longitudinal waves of pressure, some of which can be perceived as sound. If the molecules are ionized, they will also produce electromagnetic radiation.
What happens to gas particles when air leaks out an inflated ball?
The gas molecules are constantly in motion, colliding with each other and the walls of the ball. The pressure inside the ball is also much greater than the pressure outside the ball. When there's a hole in the ball, the molecules keep colliding, and some make there way out through the hole. Remember that the molecules want to go to the area of lowest pressure so that they can be at equilibrium.
What does atmospheric pressure measure?
The force of colliding particles
Why does sounds travel faster in warm air than in cool air?
The average mean speed of the molecules of air is faster in warm air than on cool air. Sound is transferred by collisions of molecules. Therefore sound waves will travel faster on warm air because collisions of molecules of air in warm air is greater.
What waves causes compressional waves caused by colliding air molecules?
Sound Waves
What is a compressional wave caused by colliding air molecules?
Sound Waves
Compressional waves caused by colliding air molecules?
Yes indeed, Sound waves will have alternate compression and rarefaction pressures. The air pressure goes above and below the average air pressure.
Do sound waves have mass?
Waves do not have mass and volume. They transmit energy without transmitting mass. However, waves can be found in solid materials such as earthquakes.
Describe how sound waves are travel?
Sound waves are caused by vibrations and travel as longitudinal waves which cause by the vibration of the molecules in air (the molecules dont actually move)
Does sound waves make air molecules vibrate?
vibrations make air molecules move
Why are sound waves compressional waves?
Sound waves are compression waves because the molecules of air are compressed.
Air pressure is caused by?
air pressure is caused by the constant motion of air molecules
What are all sounds caused by?
air waves.
What causes oceans waves?
Normal (i.e. not tsunami) waves on the ocean are caused by the wind blowing over the ocean surface. The wind transfers some of its energy to the water surface, through friction between the air molecules and the water molecules. Stronger winds caused by storms result in larger waves and the larger the stretch of ocean over which the wind is blowing, the larger the waves.The winds cause waves on the surface of the ocean (and on lakes). The wind transfers some of its energy to the water, through friction between the air molecules and the water molecules. Stronger winds (like storm surges) cause larger waves. You can make your own miniature waves by blowing across the surface of a pan of water.
What type of energy is caused by air molecules vibrating?
The type of energy caused by air molecules vibrating is called sound energy.
What causes vortex to form?
when a cold air front meets a warm air front
