Percentage saturation is __________ the relative saturation.

ANS:A - always smaller than

Percentage saturation and relative saturation are related concepts in the context of humidity and moisture content, particularly in gases.

• Percentage saturation: This refers to the actual amount of water vapor present in the air compared to the maximum amount of water vapor the air can hold at a given temperature. It is expressed as a percentage.
• Relative saturation: This is the ratio of the actual vapor pressure of water vapor in the air to the saturation vapor pressure of water vapor at the same temperature. It is also expressed as a percentage.

Since both percentage saturation and relative saturation are expressed as percentages, they are directly related. In fact, they are often used interchangeably in some contexts. Therefore, the correct statement is: Percentage saturation is not related to the relative saturation.
