The movement of gas through a small hole into an area of lower pressure is diffusion.
No, diffusion deals with concentrations not pressures.
The movement of air from an area of higher pressure to one of lower pressure
Movement of air, which naturally goes from a higher pressure to a lower pressure.
Liquid waste is removed from the urinary system by the method of filtration. This is due to the movement of liquid from a region of higher pressure to lower pressure.
Pressure is caused by random molecular movement (all directions) and wind is overall movement in one direction: from high to lower pressure. This is what you do when whistling for instance.
DiffusionThe movement of particles from a region of higher concentration to a region of lower concentration is called diffusion. However, the movement of water through a semi-permeable membrane (from an area of high concentration to an area of low concentration) is specifically called osmosis.
Because of differences in pressure, air starts to move from areas of higher pressure toward areas of lower pressure
Movement of water is a passive process called osmosis. It always moves from an area of higher concentration of water to a lower concentration of water.
In the Atmosphere this is called Wind, and it results from the active feature of the Atmosphere - the low pressure weather system. At the center of a Low, air rises. They are called 'the active features' because High pressure systems occur only 'by default': this means that High pressure systems exist everywhere that Low pressure systems do not.
a hifh pressure system
Well, the movement of water is called osmosis. movement from high concentration to low concentration is called active transport.
Are called osmosis
Reverse-Osmosis Osmosis is the movement of solvent molecules from a region of lower concentration to that of a higher concentration through a semi-permeable membrane.
