Stoichiometry - Engineering

Q1:

Percentage saturation of a vapor bearing gas is always __________ the relative saturation.

A higher than

B smaller than

C equal to

D either (a) or (b); depends on the system

ANS:B - smaller than

The percentage saturation of a vapor-bearing gas refers to the ratio of the actual vapor pressure to the saturation vapor pressure, expressed as a percentage. Relative saturation, on the other hand, is the ratio of the actual vapor pressure to the saturation vapor pressure, expressed as a fraction. Since the percentage saturation is calculated by multiplying the relative saturation by 100, the percentage saturation is always equal to the relative saturation. So, the correct option is: equal to.
