Moisture--Weather #3

The temperature to which air must be cooled in order to become saturated is the:

• Relative Humidity

• Mixing Ratio

• Dew Point Temperature

• Wet-bulb Temperature

What is relative humidity?

• humidity that is related to other humidity

• condensation

• clouds

• the amount of water in the air compared to the amount of water the air can hold

When a substance changes from a gas to a liquid it is called

• Evaporation
• Condensation
• Freezing
• Melting

What is the relative humidity when the dry-bulb temperature is 16°C and the wet-bulb temperature is 14°C?

• 90%

• 80%

• 14%

• 71%

Dew Point is the

• temperature air cools down to reach condensation (or turn into a liquid)
• temperature where ice melts to liquid water
• temperature where ice turns directly into water vapor
• time of day when dew on the ground disappears
