Late on an autumn day, the relative humidity is 44.0% and the temperature is 20.0°C. What will the relative humidity be that ev
ening when the temperature has dropped to 10.0°C, assuming constant water vapor density?
1 answer:
Answer:
humidity is 80.95 %
Explanation:
given data
humidity = 44% = 0.44
temperature = 20.0°C
temperature = 10.0°C
to find out
relative humidity
solution
we know humidity formula that is
humidity = × 100 ...................1
so here at 20.0°C
vapor density is
vapor density = humidity × saturated vapor density
here
saturated vapor density at 20.0°C is 17.3 gm/m³
so
vapor density = 0.44 × 17.3
vapor density = 7.61
and
for 10.0°C
saturated vapor density at 10.0°C is 9.4 gm/m³
so from equation 1
humidity = × 100
humidity = × 100
humidity = 80.95 %
