MCQ
Which of the following process is non-spontaneous?
  • A
    Heat flow from hot end to cool end.
  • B
    Water flow from higher level to lower level.
  • C
    Gas flow from lower pressure region to higher pressure region.
  • D
    Gas flow from higher pressure region to lower pressure region.

Answer

  1. Gas flow from lower pressure region to higher pressure region.

Explanation:

Gas flowing from higher pressure region to lower pressure region is a natural process. Similarly, option A and B are natural.

Natural processes are spontaneous. Therefore, flow of gas from lower pressure to higher pressure region is non-spontaneous.
