Question

1. what is the relative humidity when the dry - bulb temperature is 16°c and the wet - bulb temperature is 14°c?

90%
14%
80%
13%

Explanation:

To find relative humidity from dry - bulb ($16^{\circ}\text{C}$) and wet - bulb ($14^{\circ}\text{C}$) temperatures, we can use a psychrometric chart or recall the relationship between these temperatures and relative humidity. The difference between dry - bulb and wet - bulb temperature (wet - bulb depression) here is $16 - 14=2^{\circ}\text{C}$. Using the principles of psychrometry (related to meteorology/atmospheric science, a sub - field of Natural Science), when dry - bulb is $16^{\circ}\text{C}$ and wet - bulb depression is $2^{\circ}\text{C}$, the relative humidity is approximately 90%. The other options (14%, 80%, 13%) do not match the expected value from psychrometric calculations for these temperature conditions.

Answer:

A. 90%
