Length, mass, time, intensity of light and amount of substance are examples of ____________?
Correct answer: A. Base quantities
- A. Base quantities
- B. Derived quantities
- C. Prefixes
- D. Quartile quantities
Explanation
Length, mass, time, luminous intensity and amount of substance are SI base quantities because their units are fundamental and are not formed from other physical quantities. Derived quantities such as velocity and force are the likely alternative, but they are calculated from base quantities.

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
