What is humidity?What is humidity?• Humidity is the amount of water vapor or
moisture in the air.
• The air’s ability to hold water depends on air temperature.
• As the temperature increases, so does the air’s ability to hold water.
What is relative humidity?What is relative humidity?• Relative humidity compares how much water
vapor is in the air to how much vapor the air can hold.
• Relative humidity is given as a percentage.
• Saturated air has a relative humidity of 100%.
What is dew point?What is dew point?• Dew point is the temperature when the water
vapor turns back into a liquid – condensation.
• Air can become saturated when water vapor is added to the air through evaporation or transpiration.
• Air can also become saturated as in the case of the glass of water, when it cools to its dew point.
What is a psychrometer?What is a psychrometer?
• A psychrometer is an instrument used to measure relative humidity.
• It is used to make two readings of temperature. One is a dry bulb reading and the other is a wet bulb reading.
