Q.

Consider the following statements and arrange in the order of true/false as given in the codes

S1 : Change in state function between two states is a definite quantity and does not depend on path. 

S2 : Intensive properties can't be algebraically added or subtracted. 

S3 : Ratio of two extensive properties always result into a parameter that depends on amount of substance. 

S4 : Molar heat capacity is a path function. The correct order of true / false of the above statements is :

Detailed Solution

S1: Path functions like heat and work depend on the path, but state functions like volume, temperature, entropy, and Gibb's free energy are path independent.

S2: The amount of substance has no bearing on the intensity of a property. They cannot be combined or divided algebraically.
For instance: Molar and specific heat capacity, density, viscosity, pressure, and temperature.

S3: Extensive  Extensive =Intensive

Intensive qualities are unrelated to drug concentration.

S4: A state function is molar heat capacity.
