What occurs when the air temperature is equal to the dew point temperature? (1 point)
• The relative humidity is 0%, so evaporation occurs.
• The relative humidity is 0%, so condensation occurs.
• The relative humidity is 100%, so condensation occurs.
• The relative humidity is 100%, so evaporation occurs.
The correct answer is:
• The relative humidity is 100%, so condensation occurs.
Why might dew form in the morning? (1 point)
• The temperature rose overnight, and warmer air can hold more water vapor.
• The temperature rose overnight, and warmer air can hold less water vapor.
• The temperature fell overnight, and colder air can hold less water vapor.
• The temperature fell overnight, and colder air can hold more water vapor.
The correct answer is:
• The temperature fell overnight, and colder air can hold less water vapor.
Can the dew point temperature be greater than the air temperature? (1 point)
• Yes, as the dew point temperature does not depend on the air temperature.
• No, as this would mean that the air does not hold any water vapor.
• No, as this would mean that the air holds more water vapor than it can.
• Yes, as the dew point temperature depends only on the humidity.
The correct answer is:
• No, as this would mean that the air holds more water vapor than it can.
