Question

Saturated vapor is compressed to half its volume without any change in temperature, then the pressure will be

• A. doubled
• B. halved
• C. the same
• D. Zero

Answer 1

Answer: (C)

The saturation vapour pressure is the static pressure of a vapour when the vapour pressure of some material is in equilibrium with the liquid phase of that material. The saturation vapour pressure of any material is solely dependent on the temperature of that material. Since, temperature change does not occur in the given case, hence pressure will be the same.
