Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of these factors could speed up diffusion? (Choose 3)
A
Higher temperature
B
Bigger particles
C
Larger surface area
D
Steeper concentration gradient
Explanation: 

Detailed explanation-1: -The greater the difference in concentration, the quicker the rate of diffusion. The higher the temperature, the more kinetic energy the particles will have, so they will move and mix more quickly. The greater the surface area, the faster the rate of diffusion.

Detailed explanation-2: -The difference in the concentration of a substance between two areas is called the concentration gradient . The bigger the difference, the steeper the concentration gradient and the faster the molecules of a substance will diffuse.

Detailed explanation-3: -Concentration Gradient Process and Diffusion Types There are three types of diffusion: passive diffusion, facilitative diffusion, and active transport.

Detailed explanation-4: -The rate of diffusion is affected by the concentration gradient, membrane permeability, temperature, and pressure.
