Beth’s hygrometer is reading a temperature of 30°C and a relative humidity of 65%. The humidity in the air is how many grams/cub
emmasim [6.3K]
This is asking for the absolute humidity. So if the relative humidity is 65 % and the air temperature is 30 then we need to have in mind the barometric pressure which will be 760. The humidity in the air will be 0.020 kg/m3. In order to know this we calculate it eith the mass of water vapour in a unit volume of air. This is a measure of the actual water vapour content of the air. the for mula would go like this: AH = Mv / V.

A gas at 89.0 °C occupies a volume of 0.67 L. At what Celsius temperature will the volume increase to 15.9 L?
scoray [572]

Answer:

The answer to your question is T2 = 5755.8 °K

Explanation:

Data

temperature 1 = 89 °C

Volume 1 = 0.67L

temperature 2 = ?

Volume 2 = 15.9 L

Process

Use Charles' law to solve this problem

                      V1/T1 = V2/T2

-Solve for T2

                      T2 = V2T1/V1

-Convert temperature to °K

temperature 1 = 89 + 273 = 362°K

-Substitution

                      T2 = (15.9 x 362) / 0.67

-Simplification

                       T2 = 5755.8 / 0.67

-Result

                        T2 = 5755.8 °K
