##### Analytical Chemistry:

An extensive thermodynamic property is one whose value is equal to the sum of its values ​​for the parts of the system. Therefore, if we divide the system into parts, the mass of the system is the sum of the masses of the parts; matter is a vast possession. So does volume. An intensive thermodynamic property is one whose value does not depend on the size of the system, provided that the system remains from size-inducible macroscopic to nanoscopic systems.

#### CHE301 MIDTERM PAST PAPERS:

Density and pressure are examples of intensive properties. If every intensive macroscopic property is constant throughout the system, the system is homogeneous. If the system is not homogeneous, it may consist of several homogeneous parts. The homogeneous part of the system is called a phase A system composed of two or more phases is heterogeneous.

#### CHE301 MIDTERM PAST PAPERS BY MOAAZ: –

Assume that the value of each thermodynamic property in a certain thermodynamic system is equal to the value of the corresponding property in the other system. The systems are then said to be in the same thermodynamic state Lecture 6. Temperature: Assume that two systems separated by a movable wall are in mechanical equilibrium with each other Because we have mechanical equilibrium, there are no unbalanced forces and each system exerts an equal and opposite force on the dividing wall.

#### CHE301 MIDTERM SOLVED PAPERS: –

Two systems in thermal equilibrium with each other have the same temperature; two systems that are not in thermal equilibrium have different temperatures. Although we have asserted the existence of temperature as a thermodynamic state a function that determines whether or not there is thermal equilibrium between systems, we need experimental proof that such a state function actually exists.
