Answer:

4.1 * 10^-22 J

The wave belongs to the infra red portion of the electromagnetic spectrum.

Explanation:

From the formula;

E = hc/λ

We know that;

h= plank's constant = 6.6 * 10^-34 Js

c= speed of light = 3 * 10^8 m/s

λ = wavelength of the wave = 4.80 x 10^5 nm or 4.80 x 10^-4 m

Hence;

E= 6.6 * 10^-34 * 3 * 10^8/ 4.80 x 10^-4

E= 4.1 * 10^-22 J

The wave belongs to the infra red portion of the electromagnetic spectrum.

There are always attractive forces between a collection of atoms or molecules which may not be negligible as suggested by the ki
Harrizon [31]

Answer:

Negligible

Explanation:

According to the kinetic theory of gases, the degree of intermolecular interaction between gases is minimal and gas molecules tend to spread out and fill up the volume of the container.

If the attraction between gas molecules increases, then the volume of the gas decreases accordingly. This is because, gas molecules become highly attracted to each other.

This intermolecular attractive force may be so strong, such that the actual volume of the gas become negligible compared to the volume of the container.
