Que- When the air temperature is below freezing, the saturation vapour pressure over water is .
a. Equal to zero
b. Less than the saturation vapour pressure over ice
c. Greater than the saturation vapour pressure over ice
d. Equal to the saturation vapour pressure over ice
Answer- Greater than the saturation vapour pressure over ice
