Fundamentals

Le résumé fourni par la source

This chapter focuses on the units which are fundamental to the understanding and application of physical chemistry. It describes the Système International d'Unités (SI) system of units. This has been in use since 1970 and consists of seven base units, of which six are commonly used in chemistry. These measure mass, length, time, electrical current, temperature, and amount of substance. There is a seventh unit, namely luminous intensity, but this is only rarely relevant in chemistry. The chapter includes activities that determine the derived units for kinetic energy. These activities show that the unit for potential energy is equivalent to that of kinetic energy.
