Difference between dew point and boiling point?

Answer 1

Boiling point is the temperature(at a particular pressure) of a pure substance at which it boils . e.g water at 1 atm will boil at 100 degreeC. If u start heating water

its temperature will rise from ambient to 100 degC only until it totally boils to steam.

For a mixture of two components there will not be a single b.p. During boiling its temp will rise so the mixture will have an initial b.p and a final b.p.

For a pure component you only have boiling point, if u cool steam from say 120 degC, water will condense out at 100 degC.

If you cool air which contains water which we call water vap or moisture, the water will condense at a particular temp which we call as dew point. This temp will depend on the amount of water vap in the air.

Answer 2

<<<<<<<<<<<<<<<<<Dew point is little tiny drops formed from water vapor and water vapor is little tiny drops OS water so really there is no difference>>>>>>>>>>>>>>>>>>

Answer 3

There is no difference - people just shorten it to "dew point" most of the time.

Answer 4

They are both temperatures at which water changes state

Answer 5

Quite the opposite. The dew point is the temperature at which water vapor will condense from a gas to a liquid. Boiling point is the temperature at which water turns from a liquid to a gas.

Answer 6

Boiling point is related to the point in which pure substance coexist liquid and vapour
