Question

In an open system, the vapor pressure is _____ the outside air pressure.

A. Higher
B. Lower
C. Equal
D. Below

Answer 1

The vapor pressure is EQUAL TO the outside air pressure.

Answer 2

Answer: Option (c) is the correct answer.

Step-by-step explanation:

In an open system, the vapor pressure is equal the outside air pressure because there can be mass transfer or energy transfer from the atmosphere to the system as the system is open.

Whereas in a closed system there cannot be mass transfer or energy transfer from the system to the surrounding or vice versa.

Thus, we can conclude that option (c) is the correct answer.
