If air is
heated without changing its moisture content, the dew point will ________ .
यदि हवा की नमी को बदले बिना उसे गर्म किया जाए, तो ओस बिंदु ________ होगा।
increase
decrease
remain the same
unpredictable
remain the same
The Dew Point (DP) is the temperature at which water vapour
starts to condense out of the air.
When the air
is heated without changing its moisture content the dew point will not change.Because dew
point is independent of the ambient temperature. Only changes in pressure or
the actual amount of water vapour present will affect the dew point.
Hence, the correct option is (C).
&Key Points:-
●If the
dew-point temperature is close to the dry air temperature, the relative
humidity is high
●If the dew
point is well below the dry air temperature, the relative humidity low
