Question

According to one theory, the pressure of a gas increases as its volume decreases because the molecules in the gas have to move a shorter distance to hit the walls of the container. Does this theory follow a macroscopic or microscopic description of chemical behavior? Explain your answer.

Short answer

Microscopic description.

Step-by-step solution

The macroscopic domain:

It's the realm of ordinary objects large enough to be felt or seen instantly by humans. This includes consuming food and the feeling of the breeze on your face, etc. Physical and chemical properties or changes (like density, solubility, and flammability) are monitored and quantified daily or in a chemistry laboratory.

The microscopic domain:

Almost always, the microscopic realm of chemistry is visited by the imagination. Micro is a Greek word that means "little." Microscopes generally reveal different elements of the microscopic realms, like a magnified image of molecules of different chemical compounds or bacteria. Viruses, for example, are too small to be seen with the human eye, yet we're reminded of their existence when we get a cold.

Explanation:

We cannot witness the gas being filled into the container because we know gas is a transparent matter with particles scattered in the empty space. So, an increase in the pressure and volume will not show any effect. So, it is a microscopic description.
