what are state properties in thermodynamics
Answers
Within thermodynamics, a physical property is any property that is measurable, and whose value describes a state of a physical system. Properties is defined as the characteristic feature of a system by which it can be specified. Some constants, such as the ideal gas constant, R, do not describe the state of a system, and so are not properties. On the other hand, some constants, such as Kf (the freezing point depression constant, or cryoscopic constant), depend on the identity of a substance, and so may be considered to describe the state of a system, and so may be considered physical properties.
"Specific" properties are expressed on a per mass basis. If the units were changed from per mass to, for example, per mole, the property would remain as it was (i.e., intensive or extensive).
Answer: Intensive properties and Extensive properties.
Explanation:
Thermodynamic properties are divided into two broad types: intensive properties and extensive properties.
An extensive property is any property that depends on the size (or extent) of the system under consideration. Volume is an example. If you double the length of all edges of a solid cube, the volume increases by a factor of eight. Mass is another. The same cube will undergo an eight-fold increase in mass when the length of the edges is doubled.
An intensive property is any property that can exist at a point in space. Temperature, pressure and density are good examples. You could imagine moving a thermometer about a room or a pressure sensor about a swimming pool so as to record the property at each location (point in space). You also know that the density of the atmosphere is different from point to point, with air nearest the ground having the highest density and air far above the earth's surface having the lowest.
