Answer: Well,diffusion does not happen in solids because the particles are not free to move around and so they cannot inter-mix.
The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses. Mass is the word for how much substance (or matter) something has.
Isotopes are atom families that have the same number of protons, but different numbers of neutrons
Each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
Answer:
Wind moving over a water or land surface can also carry away water vapor, essentially drying the air, which leads to increased evaporation rates.
It is a true fact that ionic crystals are excellent insulators and can hold a large amount of heat before melting or boiling. The correct option among the two options that are given in the question is the first option. Salt is a great example of ionic crystals and we know that it takes a huge amount of time to melt or boil.
