Rate of diffusion is dependent upon molecular?
size, temperature, and concentration gradient. Smaller molecules diffuse faster than larger molecules, as they can more easily navigate through the spaces between other molecules. Higher temperatures increase the kinetic energy of the molecules, leading to faster diffusion. A steeper concentration gradient, where there is a large difference in concentration between two areas, also promotes faster diffusion.
Do substances diffuse in response to a stimulus?
Substances can diffuse in response to a stimulus, such as a concentration gradient or a change in temperature. The movement of particles from areas of high concentration to low concentration is driven by diffusion, and this process can be influenced by various external stimuli.
Why need high temperature in diffusion process?
High temperatures are needed in the diffusion process to provide sufficient energy for atoms or molecules to overcome energy barriers and move from areas of high concentration to low concentration. This allows for faster diffusion rates and more homogenous mixing of materials. Additionally, higher temperatures can increase the atomic mobility and promote solid-state diffusion in materials.
Why does raising the temperature cause diffusion to move faster?
Raising the temperature increases the kinetic energy of particles, causing them to move faster and collide more frequently. This increased collisions lead to faster diffusion as particles are more likely to spread out into areas of lower concentration.
What are 5 factors that affect diffusion?
Concentration gradient: The greater the difference in concentration between two areas, the faster diffusion occurs. Temperature: Higher temperatures generally increase the kinetic energy of particles, leading to faster diffusion. Molecular size: Smaller molecules diffuse more quickly than larger ones, as they can move more easily through spaces. Medium through which diffusion occurs: Diffusion occurs more readily in gases and liquids compared to solids. Surface area: The larger the surface area available for diffusion, the faster the rate of diffusion.

What areas do the neurotransmitters diffuse through?
Primarily the Brain: from the Axons to the Dendrites.

Why can oxygen diffuse across a membrane?
Oxygen is a small, nonpolar molecule that can easily pass through the lipid bilayer of cell membranes by simple diffusion without the need for a specific transport protein. This allows oxygen to move from areas of high concentration to areas of low concentration, such as from the lungs into the bloodstream.
Is gas diffusable?

Which term describes a measurement of the movement of atoms or molecules within an object?
Diffusion is the term that describes the movement of atoms or molecules within an object. It refers to the process by which particles spread out or move from areas of higher concentration to areas of lower concentration.
What A molecule that has electrically charge areas is called a?
electrical molecule
Glucose is a molecule that can move across the cell membrane if the concentration of glucose is high or inside the cell than outside the cell then what will happen by the process of diffusion?
glucose molecules will diffuse out of the cell. apex
Why does raising the temperature cause diffusion to move faster?
Raising the temperature increases the kinetic energy of particles, causing them to move faster and collide more frequently. This increased collisions lead to faster diffusion as particles are more likely to spread out into areas of lower concentration.
How do ions diffuse across cell membranes?
Ions diffuse across cell membranes through protein channels or transporters that allow them to move from areas of high concentration to areas of low concentration. This process is known as passive transport and does not require energy from the cell.
