What is the average de Broglie wavelength of oxygen molecules in air at a temperature of 27°C? Use the results of the kinetic th
asambeis [7]

Answer:

\lambda = 2.57 \times 10^{-11} m

Explanation:

Average velocity of oxygen molecule at given temperature is

v_{rms} = \sqrt{\frac{3RT}{M}}

now we have

M = 32 g/mol = 0.032 kg/mol

T = 27 degree C = 300 K

now we have

v_{rms} = \sqrt{\frac{3(8.31)(300)}{0.032}

v_{rms} = 483.4 m/s

now for de Broglie wavelength we know that

\lambda = \frac{h}{mv}

\lambda = \frac{6.6 \times 10^{-34}}{(5.31\times 10^{-26})(483.4)}

\lambda = 2.57 \times 10^{-11} m

Why is an object's density expressed as a combination of two units
miss Akunina [59]
Well, first of all, EVERY physical quantity is measured in a combination
of 2 or more units, except for mass, length, time, and electric charge. 
ALL other units are made out of these.  So it should not surprise you.

[  Example:  Speed  =  (length) / (time)  ]

Density is not the mass of a substance.  It's the mass of a substance in
a standard volume of it.  So the density is made of the mass in any lump
and the volume of that lump.  That way, no matter how much of a substance
you have, you can always compare the lump you have to all other substances.

If something is being carried by westerlies, what direction is it moving??
sergejj [24]
Winds are immigrants. They're named for where they have already been and are coming from, not for where they're going.

A Westerly wind is coming from the West. Anything caught in it is being blown toward the east.
