The temperature and the dew point in an ...

The temperature and the dew point in an open room are `20^(@)C and 10^(@)C`.if the room temperature drops to `15^(@)C`,what will be the new dew point?

Text Solution

Verified by Experts

Temperature = ` 20^@C,` dew point = ` 10^@C`
The place is saturated at ` 10^@C` even if the
temperature drop dew point remains
unaffected
The air has the vapour pressure which is
the saturation VP at ` 10^@C` if saturated
vapour pressure does not change on
temperature .
