Relative Humidity and Dew Point

What is the definition of relative humidity?

• The amount of water vapor present in the air compared to the maximum amount the air could hold at that temperature

• The temperature at which air becomes saturated and condensation occurs

• The temperature at which air becomes saturated and dew forms

• The amount of water vapor present in the air

What is the definition of dew point?

• The temperature at which air becomes saturated and condensation occurs

• The amount of water vapor present in the air compared to the maximum amount the air could hold at that temperature

• The temperature at which air becomes saturated and dew forms

• The amount of water vapor present in the air

What is the relationship between relative humidity and dew point?

• They are independent of each other

• Higher relative humidity leads to a higher dew point

• Higher relative humidity leads to a lower dew point

• There is no relationship between relative humidity and dew point

How does relative humidity affect human comfort?

• High relative humidity makes it feel hotter than it actually is

• Low relative humidity makes it feel hotter than it actually is

• Relative humidity has no effect on human comfort

• Relative humidity only affects air quality

What happens when the dew point temperature is equal to the air temperature?

• The air is holding the maximum amount of water vapor it can at that temperature

• The air is dry and lacks moisture

• The air is at a low temperature

• The air is at a high temperature

What is the unit of measurement for relative humidity?

• Percentage

• Degrees Celsius

• Millimeters

• Pascals
