Pressure is an intensive property. Intuition says it should be extensive (dependent on the size of the system), but since it is defined as a ratio of two extensive properties, the extensive-ness cancels out. Pressure = Force / Area = Work / (Distance x Area) = Work / Volume Work and volume are both extensive properties; pressure is therefore intensive.
Another way to look at the problem is to consider the consequences of the definitions of intensive and extensive properties. When two identical systems are added to each other, extensive properties are doubled (they are additive) and intensive properties stay the same (they are independent of size). So, if two systems, each containing 1L and 1 mole of an ideal gas at 25 degrees C are added to each other, we get the following results: 1. Volume is extensive. (Proof: 1L + 1 L = 2 L)
2. Quantity is extensive. (Proof: 1 mole + 1 mole = 2 moles)
3. Temperature is intensive. (Proof: everything stays at 25 degrees C) Volume doubles, but so does the number of moles. The pressure remains the same, even after doubling the size of the system! (PV = nRT; see the Ideal Gas Law to confirm this conclusion.) Pressure is therefore an intensive property, ie. independent of the size of the system.

Is melting point a extensive or a intensive property?
The melting point is an intensive property.
Is malleability a intensive property or extensive property?
Melting point is an intensive propery because doesn't depend on the mass of sample.
What are examples of intensive physical properties of a substance?
An intensive physical property does not depend on the size of the sample. An example of an intensive physical property is density. An extensive physical property does depend on the size of the sample, such as mass and volume.
Is color a intensive or extensive property?
The properties of a substance can be divided up into two basic kinds: Intensive properties are those that do not depend on how much of the substance you have. For example, the boiling point is an intensive property: water boils at the same temperature no matter if you have 1 gram, 10 grams or 100,000 kilograms of water. Other examples of intensive properties include density, solubility, color, and melting point. Extensive properties depend on the amount of the substance. For example, the volume of a sample is an extensive property: 100 grams of water takes up more volume than 1 gram of water. Mass is also an extensive property.
What is an example of freezing point?
The freezing point is the same thing as the melting point and the example for oxygen is <-361 degrees Fahrenheit.
Is melting point a extensive or a intensive property?
The melting point is an intensive property.
Is melting point an intensive or extensive property?
The melting point is an intensive property.
Is Melting point is an extensive or intensive property?
The melting point is an intensive property.
Is melts a intensive property or extensive property?
The melting point is an intensive property.
Is melting point a extensive property?
Melting point is an intensive property.
Is the boiling point of water is extensive?
Boiling point is an intensive property.
Is malleability a intensive property or extensive property?
Melting point is an intensive propery because doesn't depend on the mass of sample.
Is velocity intensive or extensive property?
like temperature, density, boiling and melting point velocity is an Intensive property.
Is conductivity intensive property?
Conductivity is an intensive property. Intensive properties are associated with the physical properties of a substance, and include things like melting point, ductility, malleability, density, and freezing point. These are characteristics of a substance that do not depend on the amount of the matter present.
If you had an unknown substance and were asked to identify it would you use the intensive or extensive properties of the substance?
Intensive properties are independent from the mass of an object: density, hardness, melting point.
Is density an intensive property?
Yes. Intensive properties are properties which do not depend on the size of the system. Say you had a piece of ice, whether that piece of ice was extremely small or extremely large, the density of the ice would be the same, so it's considered an intensive property.
What are examples of intensive physical properties of a substance?
An intensive physical property does not depend on the size of the sample. An example of an intensive physical property is density. An extensive physical property does depend on the size of the sample, such as mass and volume.
