molecules, creating a sound wave. Sound isn't restricted to moving through the air. Press your ear against a solid surface like a table and close your eyes. Tell someone else to tap his or her finger on the other end of the table. The tapping becomes the initial disturbance. Eac...
When water is cooled,the water molecules move slower and get closer together. This makes cold water more dense than room temperature water. Since cold water is more dense, it sinks in the room temperature water. Why does ice float on water? Believe it or not, ice is actually about 9% l...
Why is cold air more dense? Why do nuclear reactions release more energy than chemical? Why does temperature affect the rate of diffusion? How do gas laws apply to biology? How do gas laws apply to cars? Why do molecules in solids not diffuse into one another?
3) First of all, water is incompressible, it means that pressure in the ocean increase with increasing depth as well. Therefore, if all the ice melted, the sea level will drop because water density is way sensitive to changes. When water is heated, molecules move apart and speed up as ...
Why do hot molecules move faster than cold molecules? Can you explain why water flows in a continuous stream down a vertical pipe, whereas it breaks into drops when falling freely? Why would time slow down at the speed of light? What is the shape of raindrops with a radius less than 0.5...
molecules move to the surface and replace evaporated molecules. Drying appears to occur at the edges (see the video, seconds 19 to 30). This appearance of drying at the edges is probably an illusion. As the drop area loses water, the cohesive force between remaining water molecules of water...
Air molecules are like rubber balls. They move faster when lower and slower when higher. Air not shown. This random movement is what we in the biz’ call “heat energy”. Heat is literally just the random motion of atoms. When an air molecule is close to the ground it’s mo...
The main aim for an exhaust system is to get the exhaust gasses away from the engine in a smooth and swift fashion, with restrictions and expansions like a large catalytic converter only causing turbulence and therefore disturbed, slower airflow. Sport cats do their best to solve this issue ...
means oil molecules are “repelled” from the surface. To be completely accurate, molecules are not repelled, rather there is a complete lack of any attraction. Teflon™ Coatings in Semiconductor Manufacturing PFA topcoats are also popular for semiconductor factory applications because of their ver...
