Is an isolated system can be transferred between the system and its surrounding?
A system is classified as closed, open or isolated based on the interaction of mass and energy through the system boundary. In a closed system no mass can transfer across the system boundary but energy can transfer through it. In case of an isolated system, no mass or energy can transfer across the boundary.
Which one is an isolated system?
In physical science, an isolated system is either of the following: a physical system so far removed from other systems that it does not interact with them. a thermodynamic system enclosed by rigid immovable walls through which neither mass nor energy can pass.
When path is completely specified it is called?
When the path is completely specified, then the change of state is called a Process. A Process is defined as the transformation of the system from one fixed state to another fixed state.
Which is an extensive property of system?
By contrast, an extensive property of a system does depend on the system size or the amount of material in the system. According to the definitions, density, pressure and temperature are intensive porperties and volume, internal energy are extensive properties.
Is Pressure extensive property?
Pressure is indeed an intensive property because it is force divided by an extensive quantity (area).
Which type of property is entropy?
Entropy is a thermodynamic property, like temperature, pressure and volume but, unlike them, it can not easily be visualised.
Which property is called intensive property?
The ratio of two extensive properties of the same object or system is an intensive property. For example, the ratio of an object’s mass and volume, which are two extensive properties, is density, which is an intensive property.
Is heat an intensive state variable?
the answer is no. is it extensive or intensive? Since the concept of intensive and extensive properties only applies to physical properties that are a function of state, heat is neither intensive nor extensive.
Is work an intensive state variable?
pressure p (intensive) and volume V (extensive) are thermodynamic state variables – independent on the way how a state was achieved. pdV =W is work and NOT a state variable, but a process variable – and depends on the way it was achieved. .
Is work a thermodynamic variable?
Formal definition Consequently, thermodynamic work is defined in terms of quantities that describe the states of materials, which appear as the usual thermodynamic state variables, such as volume, pressure, temperature, chemical composition, and electric polarization. One simple example is pressure–volume work.
Is work done an intensive property?
Answer: b) Extensive Property: enthalpy, volume, internal energy, work, heat, entropy, mass. Intensive Property: Pressure, temperature, specific volume, density and specific heat.
