Will the dew point change with increasing tempureature if the amount of moisture in the air doesnt change?

Question

please explain your answer!!
thanks!

Answer 1

Good question and here is your scientific answer. The immediate answer is "no, the amount of moisture in the air will not change". Now think of temperature and dew point in this way. Temperature is a measure of how much moisture the air CAN hold while dew point is a measure of how much moisture the air DOES hold. So if the latter is true then raising the temperature does not change the amount of moisture BUT it does change the relative humidity by reducing it. Likewise if the temperature were to drop, the moisture content would remain the same, but the relative humidity would increase. Remember that when the temperature drops to the dew point, the relative humidity is 100%. Now I hope this helps with your understanding of the dew point, temperature, and relative humidity.

Answer 2

The dew point, in short, is the temperature that the air needs to be cooled to (at constant pressure) for moisture to "come out" of the air...in the form of fog, clouds, precipitation, etc. So, in this case, if you change the temperature, but are not adding any moisture (or removing), the dew point will stay the same. The relative humidity, however, will go up or or down (down if you raise the temp, up if you lower the temp). The relative humidity is just a relation between the temperature and dew point...a percentage of how much moisture the air is currently "holding". The relative humidity is not really a good way to judge how "moist" the air it though. Does 100% humidity in the winter feel "humid" to you? Not really. A better way to judge is by looking at the dew point. The higher that is, the more water vapor is in the air, and the more "humid" it will feel. Dewpoints upwards of 65 F in the summer is getting pretty humid, with 70 or above rather oppressive under most conditions.

Answer 3

Dew point is defined as the temperature at which air would become saturated,if it were cooled sufficiently,a further lowering of this temperature being responsible for spontaneous condensation.
Hence dew point temperature depends only upon the amount of moisture in the air.
So ,the answer is 'No'.

Answer 4

I believe dew point is the temperature at which water vapor condenses from the air, so no. Dew point is a temperature.
