Ideal gases; pressure of a gas confined by a liquid; Avogadro's Law; and Graham's Law are described. The book also discusses aggregated states of matter, atoms and molecules, chemical equations and arithmetic, thermochemistry, and chemical periodicity. The book is a good source of information for readers wanting to study chemistry.
