Question

At what temperature is a gas likely to have the lowest rate of diffusion? (4 points)

a
15°
21°
оооо
249
d
30°

Answer 1

15º

Step-by-step explanation:

The rate of diffusion is lower when the temperature is lower. Since 15º is the lowest temperature of the answers, it has the lowest rate of diffusion.

Answer 2

15°

Step-by-step explanation:

At the lowest temperature the gas will have the lowest rate of diffusion because diffusion deals with the motion of particles.

• Diffusion is the movement of particles from a region of high concentration to that of a lower concentration.

• According to the kinetic molecular theory of gases, the temperature of a gas is a measure of the average kinetic energy of the molecules.
• The higher the temperature faster the molecules diffuse.

The gas with the lowest temperature will be the slowest to diffuse.
