What occurs when the air temperature is equal to the dew point temperature?(1 point)

Responses

The relative humidity is 0%, so condensation occurs.
The relative humidity is 0%, so condensation occurs.

The relative humidity is 100%, so condensation occurs.
The relative humidity is 100%, so condensation occurs.

The relative humidity is 100%, so evaporation occurs.
The relative humidity is 100%, so evaporation occurs.

The relative humidity is 0%, so evaporation occurs.

The correct response is: The relative humidity is 100%, so condensation occurs.

Why might dew form in the morning?(1 point)

Can the dew point temperature be greater than the air temperature?(1 point)

Responses

Yes, as the dew point temperature does not depend on the air temperature.
Yes, as the dew point temperature does not depend on the air temperature.

No, as this would mean that the air holds more water vapor than it can.
No, as this would mean that the air holds more water vapor than it can.

No, as this would mean that the air does not hold any water vapor.
No, as this would mean that the air does not hold any water vapor.

Yes, as the dew point temperature depends only on the humidity.

The correct response is: No, as this would mean that the air holds more water vapor than it can.

When the air temperature is equal to the dew point temperature, the relative humidity is 100% and condensation occurs. This happens because the dew point temperature is the temperature at which the air becomes saturated with water vapor, meaning it cannot hold any more moisture. When the air temperature reaches this point, the excess moisture in the air condenses into water droplets or forms dew on surfaces.
