Which of the following is an extensive property?
A.Volume
B.Surface tension
C.Viscosity
D.Density
Solution
The property of matter that depends on the amount of matter is known as an extensive property. The extensive properties change as the amount of matter or sample changes.
The property of matter that does not depend on the amount of matter is known as an intensive property.
Complete step by step answer:
Step 1:
The amount of space occupied by any matter or object or substance is known as volume. The volume changes as the amount of matter changes.
Thus, volume is an extensive property.
Step 2:
The energy required to increase the surface area of a liquid due to intermolecular forces is known as surface tension. The surface tension does not change as the amount of matter changes and thus, it is an intensive property.
Thus, surface tension is not an extensive property.
Step 3:
The resistance of a liquid to flow is known as viscosity. The viscosity does not change as the amount of matter changes and thus, it is an intensive property.
Thus, viscosity is not an extensive property.
Step 4:
The ratio of mass to volume is known as density. The density does not change as the amount of matter changes and thus, it is an intensive property.
Thus, density is not an extensive property.
Thus, volume is an extensive property.
Thus, the correct option is option (A).
Note:
The volume of any matter or substance depends on the mass or amount. Thus, volume is considered as an extensive property.
The properties surface tension, viscosity and density do not depend on the mass or amount of the matter. Thus, surface tension, viscosity and density are intensive properties.
