Question

If $x$ and $y$ are arbitrary intensive variables, then:

• A. $xy$ is an intensive variable
• B. $x/y$ is an intensive variable
• C. $x+y$ is an extensive property
• D. $dx/dy$ is an intensive property

Answer 1

Answer: (A), (B), (D)

The correct options are
A $xy$ is an intensive variable
B $x/y$ is an intensive variable
D $dx/dy$ is an intensive property

Intensive properties :- The properties of system which depend only on the nature of matter & do not depend on the quantity of matter.

Extensive properties :- The properties which depend on the quantity of matter.

If $x$ and $y$ are arbitrary intensive variables.

Therefore, $xy$ is an intensive variable.

$x/y$ is an intensive variable.

$dx/dy$ is an intensive property.
