A sample of gas initially occupies 4.25 L at a pressure of 0.850 atm at 23.0°C. What will the volume be if the temperature is ch
Akimi4 [234]

Answer:

2.31\text{ L}

Explanation:

Here, we want to calculate the final volume

We use the general gas equation here:

\frac{P_1V_1}{T_1}\text{ = }\frac{P_2V_2}{T_2}

P1 is the initial pressure which is 0.850 atm

V1 is the initial volume which is 4.25 L

T1 is the initial temperature which is (23 + 273.15 = 296.15 K)

P2 is the final pressure which is 1.50 atm

V2 is the final volume which is unknown

T2 is the final temperature (11.5 + 273.15 = 284.65 K)

Substituting the values, we have:

\begin{gathered} \frac{0.850\text{ }\times4.25}{296.15}\text{ = }\frac{1.50\times V_2}{284.65} \\  \\ V_2\text{ = }\frac{284.65\text{ }\times0.850\times4.25}{1.5\times296.15} \\  \\ V_2\text{ = 2.31 L} \end{gathered}

The amount of. moisture in the air is highest when relative humanity is
gogolik [260]

Answer:

Saturation is the maximum amount of water vapor in the air at an existing temperature and pressure. Air is said to be saturated at 100 percent relative humidity when it contains the maximum amount of moisture possible at that specific temperature. Dew point is the temperature when air reaches 100% relative humidity.
