Rticles from the burning fuel dispersed in a gas – usually air. Smoke can be described more specifically as a suspension. What will most likely happen over time to smoke in the atmosphere?

The solid particles will spread out and dissolve.
The particles will eventually come together in a cloud and produce rain.
Over time, the solid particles will settle on whatever is outside.
The particles will remain mixed in the air.

Fruit jelly is mostly juice, but it doesn’t run all over the place even if you cut a piece and put it on a plate. This is because the juice is contained within the structure of a natural substance called pectin, which can hold its shape on its own at room temperature. The dispersed state of matter is
, and the dispersion medium is
.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

here we can see that the radon nuclide has 222 as the atomic mass number and 86 as the atomic number.

when it undergoes nuclear fission it gives polonium which has atomic mass number as 218 and atomic number will be 84 along with a helium nucleus which has 4 atomic mass number and 2 as its atomic number.

222 = 218 + 4 (atomic mass number)

86 = ? + 2; therefore ? = 86-2 = 84.

the atomic mass number of polonium will be 84.
