°C, and 50% respectively. What is the dew point temperature?

To find the dew point temperature, we need to use the formula:

dew point temperature = (243.5 * [ln(relative humidity/100) + ((17.67 * dry bulb temperature)/(243.5 + dry bulb temperature))]) / (17.67 - [ln(relative humidity/100) + ((17.67 * dry bulb temperature)/(243.5 + dry bulb temperature))])

Plugging in the given values, we get:

dew point temperature = (243.5 * [ln(50/100) + ((17.67 * 30)/(243.5 + 30))]) / (17.67 - [ln(50/100) + ((17.67 * 30)/(243.5 + 30))])
dew point temperature = (243.5 * [-0.6931 + (5.0476/273.5)]) / (17.67 - [-0.6931 + (5.0476/273.5)])
dew point temperature = (243.5 * [0.0178]) / [18.36]
dew point temperature = 23.7°C

Therefore, the dew point temperature of the air in the room is 23.7°C.
