Question

Consider the following statements and arrange in the order of true/false as given in the codes.
$S_1$: Change in state function between two states is a definite quantity and does not depend on path.
$S_2$: Intensive properties cannot be algebraically added or subtracted.
$S_3$: Ratio of two extensive properties result in a parameter that depends on the amount of substance.
$S_4$: Molar heat capacity is a state function.
The correct order to true/false of the above statements is:

• A. F T F T
• B. F F F T
• C. T T F T
• D. T T T F

Answer 1

Answer: (C)

T T F T

Statement $S_1$: State functions are path independent like volume, temperature, entropy, Gibb's free energy, etc whereas path functions depend on path like heat and work.

Statement $S_2$: Intensive properties are independent of amount of matter. They cannot be algebraically added or subtracted.

For example: Pressure, temperature, density, viscosity, molar and specific heat capacity.

Statement $S_3$: $\frac{Extensive}{Extensive}=Intensive$

Intensive properties are independent of amount of substance.

Statement $S_4$: Molar heat capacity is a state function.
