Because the mass depends on the size of an object.
Mass is not an intensive property because it depends on how much of it there is... that is, the "extent". That makes it an extensive property.
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.
Density is an intensive property because the size of the sample does not matter.
the properties depending upon the quantity of substance are extensive and the ones which are not are intensive One simple technique is to think about a box filled with the substance under consideration and divide it into two halves, if the property remains same (temp, density etc) then its intensive and if diff. (volume, mass etc) then extensive...
Mass is not an intensive property, it is an extensive property, i.e. the mass of a system made of two parts A and B is equal to the mass of A plus the mass of B. An intensive property (e.g. pressure or temperature) is one in which the value of the property for the entire system is equal to the value of the property for any of the subsystems. So, you probably wanted to ask why mass is an extensive property. This is a consequence of the law of gravity and of the fact that forces add up to make a resultant force. The total gravitational force upon a body X by two other bodies A and B is the sum of the force exerted by A and the force exerted by B. It's as if we have a combined body with the mass of A plus the mass of B, and thus mass is extensive.
Temperature is an intensive physical property.
Mass is an extensive physical property.
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.
Melting point is an intensive propery because doesn't depend on the mass of sample.
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.
intensive
In the physical sciences, an intensive property (also called a bulk property, intensive quantity, or intensive variable), is a physical property of a system that does not depend on the system size or the amount of material in the system: it is scale invariant. Distance is an intensive property.
Reactivity is intensive property, reaction rate is extensive.
why electrical conductivity is an intensive property of matter
Mass is an extensive (not an intensive) property, because it is proportional to the amount of material in the system.
The two types of physical properties are intensive and extensive. Intensive properties do not depend on the amount of a substance. An example of an intensive property is density. Extensive properties do depend on the amount of a substance. An example of an extensive property is mass.
Intensive properties do not depend on the matter's amount of the physical system (mass density, temperature ...). Extensive properties do depend on the amount of matter that is present (volume, mass and size).
Density is an intensive property because the size of the sample does not matter.
