Each m3 of air, the temperature of which is + 20 ° C, contains 9.7 g of moisture. How many degrees does this air have to cool for condensation to begin in it?

1) According to the table, we find that air containing 9.7 g of moisture becomes saturated at a temperature lower than + 11 ° C.
2) 20оС – 11оС = 9оС – the air must be cooled by so many degrees so that the condensation process begins in it.
Answer: the air must be cooled by 9 ° C for the condensation process to begin in it.
