Is specific volume an independent intensive property?

a. temperature and specific volume (density-1) are always independent. Temperature at which water boils varies with pressure (100 C at sea level, ~93 C in Boulder). “Intensive” = the value of the property is not dependent on that amount of material in the system.

Is volume a intensive property?

Mass and volume are examples of extensive properties. An intensive property is a property of matter that depends only on the type of matter in a sample and not on the amount. Color, temperature, and solubility are examples of intensive properties.

Why specific extensive properties are intensive properties?

Summary. An extensive property is a property that depends on the amount of matter in a sample. Mass and volume are examples of extensive properties. An intensive property is a property of matter that depends only on the type of matter in a sample and not on the amount.

What is specific volume in thermodynamics?

In thermodynamics, the specific volume of a substance (symbol: ν or ) is an intrinsic property of the substance, defined as the ratio of the substance’s volume (V) to its mass (m).

Why do we use specific volume?

Specific volume is most often used in engineering and in thermodynamics calculations for physics and chemistry. It is used to make predictions about the behavior of gases when conditions change.

Is specific heat intensive or extensive?

The specific heat capacity is intensive, and does not depend on the quantity, but the heat capacity is extensive, so two grams of liquid water have twice the heat capacitance of 1 gram, but the specific heat capacity, the heat capacity per gram, is the same, 4.184 (J/g.K).

Is specific gravity intensive or extensive?

Intensive property is the property that does not depend on the amount of matter. Examples include temperature, density, specific gravity, pressure, melting point, and boiling point. Extensive property is the property that depends on the amount of matter.

Is specific volume intensive or extensive?

Specific volume is an intensive property of the gas, as shown in our example. The specific volume of the original tank is the same as the specific volume in each half. The “specific” of specific volume simply means “divided by mass”.

What is meant by specific volume?

: the volume per unit mass of a substance : the reciprocal of the density.

Is specific volume a state function?

A state function is a property whose value does not depend on the path taken to reach that specific value. In contrast, functions that depend on the path from two values are call path functions. Both path and state functions are often encountered in thermodynamics.

Why do we need specific volume?

It is useful in industry for easy understanding of fluids . the inverse of the density . Thus an increase in specific volume is a decrease in density. It is used for the same reason all other derived variables are used, it simplifies the formulas and gives a more clear meaning of what happens.

Is density an intensive property or an extensive property?

Both mass and volume are extensive properties. However, density is a ratio of these two properties, and the ratio does not change, making density an intensive property. As a general rule in thermodynamics , the ratio of any two extensive properties is always an intensive property.

What is the difference between extensive and intensive properties?

Intensive Properties. Intensive properties are bulk properties,which means they do not depend on the amount of matter that is present.

Extensive Properties. Extensive properties do depend on the amount of matter that is present.

Way to Tell Intensive and Extensive Properties Apart.

Is length an intensive property or an extensive property?

Intensive properties can’t be added or subtracted when you add or take away some of the substance. Extensive properties depend on how much of a substance you have. For example, an extensive property is length. An object 5 cm long is shorter than an object 10 cm long and if you lay each one end to end you have a total length of 15 cm.

What is the difference between intensive and extensive property?

Extensive properties are those which depend on the amount of matter present, while intensive properties are those that do not change regardless of the amount of matter present.
