Bella Macdonald · Answer 1

B

Explanation:

Diffusion involves the movement of particles of a gas. They possess a kinetic energy which depends on the temperature of the gas. Increasing the temperature of the gas implies increasing the average kinetic energy of the molecules of the gas. If moregas molecules are present and their kinetic energy is increased by increasing the temperature, the rate of diffusion will definitely increase. Hence the answer.

Ariel Rivers · Answer 2

B. The rate of diffusion increases with the increase in number of particles and temperature. Temperature increases particle speed, and more particles means there are more to move with the temperature.
