Question

Vapour pressure depends on_______

(a) Pressure

(b) Temperature

(c) Density

(d) Viscosity

I got this question in class test.

I'd like to ask this question from Effect of Acceleration in  Suction and Delivery Pipes on Indicator Diagrams topic in chapter Indicator Diagrams of Fluid Mechanics

Answer 1

The correct answer is (b) Temperature

Explanation: Vapour pressure depends on temperature only. With the increase in temperature, the vapour pressure increases. It increases until it reaches the critical temperature. At the critical temperature, the vapour pressure tends to slowly vanish.
