5. The Santa Ana winds, also known as "devil winds", are strong and dry high-pressure masses of air that begin in the Great Basi

n mountains and then affect coastal areas in Southern California. Assume that these winds consists of a mixture of nitrogen and oxygen gases that behave ideally and that they begin at a pressure and temperature of 0.705 atm of 22.0 0C, respectively, and that this mass of air is then adiabatically and reversibly compressed to a pressure of 1.00 atm when it descends to the coastal regions. Calculate the final temperature.

Answer:

Explanation:

Given that;

The initial pressure = 0.705 atm

The initial temperature = 22.0° C

The final pressure = 1.00 atm

The objective is to calculate the final temperature,

Since the change occurs adiabatically and reversibly, the final temperature can be calculated by using the thermodynamics equation:

(\dfrac{T_2}{T_1})^r= (\dfrac{P_2}{P_1})^{r-1}

where;

r = 7/5 = 1.4

(\dfrac{T_2}{22.0^0})^{1.4}= (\dfrac{1.00}{0.705})^{1.4-1}

(\dfrac{T_2}{22.0^0})^{1.4}= (1.418)^{0.4}

T_2 = 22 \times 1.418 ^{^{\frac{0.4}{1.4}}

T_2 = 22 \times 1.418 ^{{0.286}

T_2 =24.31^0 \ C

Where are non metals found in the periodic table
Romashka [77]

The metals are to the left of the line (except for hydrogen, which is a nonmetal), the nonmetals are to the right of the line, and the elements immediately adjacent to the line are the metalloids.

hope it helps...!!!

The image below shows two nitrogen atoms. For these two atoms to form a stable molecule, N2, how many electrons would have to be
maxonik [38]
There are six electrons in the covalent bonds.

Two N atoms would be :N:· + ·:N:
An N₂ molecule would be :N:::N: or :N≡N:
This gives each N atom an octet of eight electrons in its valence shell.
