Q:

Which of the following is not an intensive property?

A) Weight B) Density
C) Refractive index D) Melting point
 
Answer & Explanation Answer: A) Weight

Explanation:

An intensive property is a physical quantity whose value does not depend on the amount of the substance for which it is measured. For example, the temperature of a system in thermal equilibrium is the same as the temperature of any part of it. If the system is divided the temperature of each subsystem is identical. The same applies to the density of a homogeneous system, if the system is divided in half, the mass and the volume change in the identical ratio and the density remains unchanged. Additionally, the boiling point of a substance is another example of an intensive property. For example, the boiling point for water is 100 °C at a pressure of one atmosphere, a fact which remains true regardless of quantity.

The Hooke's law is valid for

A) only proportional region of the stress strain curve B) entire stress strain curve
C) entire elastic region of the stress strain curve D) elastic as well as plastic region of the stress strain curve
 
Answer & Explanation Answer: A) only proportional region of the stress strain curve

Explanation:

Hooke's law states that within the elastic limit, stress developed is directly proportional to the strain produced in a body.Hooke’s law is valid only in the linear part of stress-strain curve. Hence, statement 1 is correct.
