The internuclear distance between two closest ar atoms in solid argon is about 3.8 a. the polarizability of argon is 1.66e-30 m3, and the first ionization is 1521kj/mol. estimate the boiling point of argon [hint: calculate the potential energy due to dispersion interaction for solid argon, and equate this quantity to the average kinetic energy of 1mole of argon gas, which is (3/2)rt].

i'm confused about where to use the first inonization energy?

the five characteristics of adolescence are biological growth and development, and undefined status, increased decision making, increased pressure and the search of self.

scattering of light by tiny particles in air to produce the colors we see on sky, is dependent on the following factors:

(i) wavelength of light

(ii) size of the scattering particle  

(iii) distance traveled by light through the atmosphere.

according to rayleigh's law of scattering, the amount of scattering is inversely proportional to the fourth power of its wavelength. shorter the wavelength, greater is its scattering. hence violet/blue light is scattered more than red.

sun's light is a composite light ( visible light) with wavelengths in the range 400 nm (violet) to 700 nm (red). as sunlight passes through our atmosphere, the molecules of air scatter light according to their wavelengths. during sunrise and sunset, the sun's position is below the horizon. hence light from the sun travels a greater distance in the atmosphere when compared to its position a noon.

as sunlight enters the earth's atmosphere, blue light is scattered away and at the end of its journey in the sky, only red and orange wavelengths remain in the beam.

hence at sunrise and sunset, the sky appears reddish orange.

explanation:

density =m/v

density =917/3.00

density = 305.

approximately = 305.7
