question
in the study of chemistry, you will learn about the ideal gas law, which relates pressure, temperature, and volume for gases. what is the best reason why the ideal gas law is studied in chemistry?
select the correct answer below:
gases are matter, so anything to do with gases is a part of chemistry.
the ideal gas law explains how the composition of gases changes.
the ideal gas law explains how the properties of gases change.
the ideal gas law explains how gases interact with liquids.

Explanation:

The ideal gas law ($PV = nRT$) relates pressure ($P$), volume ($V$), number of moles ($n$), temperature ($T$) and the ideal - gas constant ($R$). It describes how these properties of gases change under different conditions. It does not focus on gas - liquid interactions or gas composition changes. While gases are matter and part of chemistry, this is a very general statement and not the best reason for studying the ideal gas law.

Answer:

The ideal gas law explains how the properties of gases change.
