The process is called diffusion.
The process is called diffusion.
I believe you are talking about diffusion - when particles move from an area of high concentation to an area of lower concentration.
The tendency of a plant to grow toward a stimulus is called positive tropism. This can be in response to light (phototropism), gravity (gravitropism), or touch (thigmotropism).
It is called entropy, the second law of thermodynamics.Horse Isle Answer: entropy
A nasty smell can spread through diffusion as odor molecules move from an area of higher concentration to one of lower concentration in the air. As these molecules collide with air particles, they disperse and travel, allowing the smell to reach a wider area. Factors such as temperature, air movement, and humidity can enhance or hinder this process, affecting how quickly the odor spreads. Ultimately, the diffusion of smell is driven by the natural tendency of particles to move toward equilibrium.
Sublimation is when a substance changes directly from a solid to a gas without passing through the liquid phase. This is driven by the tendency of particles to move from areas of higher concentration to lower concentration, allowing solid snow to transition into a gas in cold, dry conditions without melting first.
It is because during active transport, the molecules are being transported against and toward the concentration gradient whereas in diffusion, the molecules go from the concentration gradient.
I assume you're talking about Osmosis, but I believe there are actually other similar processes as well.
Entropy
Osmosis
NO
Yes. It is called Osmosis. Particles move across the membrane in order to balance the concentration of particles on both sides of the membrane. Since the membrane tends to block the larger particles, its the smaller molecules that move, so what happens across membranes is that the motion (of say water) is from low concentration toward higher - but the result is to even the concentration on both sides of the membrane, Pure diffusion is always from higher concentration to lower.
