Liquid diffusivity is of the order of _______________ cm2 /second?
Correct answer: C. 10-5 to 10-6
- A. 0.01
- B. 0.1
- C. 10-5 to 10-6
- D. > 1
Explanation
Molecular diffusivity in liquids is much lower than in gases because liquid molecules are closely packed; its typical order is 10^-5 to 10^-6 cm²/s. Values near 0.1 cm²/s are characteristic of gases rather than liquids.
