Question

* select correct statement
A. diffusion in gases is very fast
B. light gases diffuse slower than heavy gases
C. Diffusion in liquid is very fast
D. diffusion pressure is indirectly proportional to the concentration gradient of diffusing particles​

Answer 1

Answer:

A. diffusion in gasses is very fast

Explanation:

Gaseous particles are in constant random motion. Gaseous particles tend to undergo diffusion because they have kinetic energy. Diffusion is faster at higher temperatures because the gas molecules have greater kinetic energy.
