Air is made up mostly of O2, N2, and CO2. If the total pressure of air is 765mmHg and P(N2) = 0.79 atm and P(CO2) = 0.05 atm, th
Mrac [35]

Answer:

the partial pressure of the O2 is 0.167 atm

Explanation:

The computation of the partial pressure of the O2 is shown below:

As we know that

P = P_N2 + P_O2 + P_CO2

P_O2 = P - P_N2 -  P_CO2

= (1.007 - 0.79 - 0.05)

= 0.167 atm

Hence, the partial pressure of the O2 is 0.167 atm

we simply applied the above formula

When steam from a pan of boiling water reaches a cool window, it condenses. How much
andriy [413]

Because the air right above your hot pan of water is so warm, the water vapor can be quickly absorbed there. When the heat is removed, the hot convective up current from the pan vanishes and is replaced with cooler air that can no longer contain as much moisture, which makes the condensing water vapour visible.

First, it's important to discuss the "steam" that is produced by the hot water. While we refer to it as steam, it is not. Water that is heated above 100 degrees Celsius produces steam. The only area in the kitchen where you can see it clearly is if you look very closely at the spout of a boiling kettle. The first 5mm (1/4") of the liquid will be clear when it is boiling very near to the spout.

An online wave simulator created these four waves. Which wave has the lowest frequency?
Luden [163]
<h2>Hello!</h2>

The wave with the lowest frequency is the second one.

<h2>Why?</h2>

Frequency is defined as the number of times that a periodic phenomenon is repeated in a given time. Regarding waves, the frequency of a wave is the number of times that a wave repeats in a unit of time. Frequency is measured in Hertz (Hz=1/s).

The relationship between frequency and wavelength is inverse, meaning that longer wavelengths mean lower frequencies. From the given list, the wave with the longest wavelength is the second one, meaning that its frequency is the lower.

Have a nice day!
