what is the main difference between extensive and intensive physical properties?
478592
Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance's chemical identity.

Pressure does not depend upon the amount of substance because it is defined as force per unit area. The definition itself eliminates the need of looking for how much of quantity is causing that much pressure. Pressure is an intensive property (independent of amount).

An extensive variable is one which depends on system size (like mass or volume). While extensive variables are useful for characterizing the specific system being analyzed, they are not general and (as we will see later in the course) do not help us to determine the "state" of the system.

There are many differences like physical and chemical . like metals are generally hard , sonorus, ductile ,lustorus ,malleable etc and non metals are soft non malleable and non ductile. Metals have generally high melting point and boiling point. and they are good conductors of heat and electricity.

As adjectives the difference between extensive and comprehensive. is that extensive is in the nature of an extent, wide, widespread while comprehensive is broadly]] or completely covering; [[include|including a large proportion of something.

All properties of matter are either extensive or intensive and either physical or chemical. ... For example, the freezing point of a substance is a physical property: when water freezes, it's still water (H2O)—it's just in a different physical state.

A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. ... A chemical property describes the ability of a substance to undergo a specific chemical change. To identify a chemical property, we look for a chemical change.

Each interface has two types of properties assigned to it: physical properties and logical properties. Physical properties are tied to the entire physical port, whereas logical properties affect only that logical portion of the interface represented by unit numbers or channel numbers.

There are four different properties of matter. They are weight, volume, mass, and density. The most important one is mass. Mass is the amount of matter in an object and it never changes unless matter is taken out of the object.

Intensive properties are used to identify a substance and do not depend upon the amount of substance (density). Extensive properties depend on the quantity of the substance (mass, volume). Chemical matter properties include flammability and reactivity.

Is emf of a cell extensive or intensive property? ... emf of a cell = E0 -RT/nF log(Keqm). Now, keqm (equilibrium ) does not change with concentration. Hence, it is an Intensive Property.

Characteristics such as mass, volume, color and temperatures are physical properties. Chemical Properties of matter are the ability of substances to react with or change into other types of matter. ... Some characteristics can describe a substance but do not, by themselves, identify the substance.
1237122
Some examples of intensive properties are color, taste, and melting point. Extensive properties vary according to the amount of matter present. Examples of extensive properties include mass, volume, and length.

A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. Physical properties include color, density, hardness, and melting and boiling points. ... To identify a chemical property, we look for a chemical change.

Physical versus chemical Sometimes it can be useful to distinguish between different types of properties. Physical properties refer to properties that can be observed or measured without changing the composition of the material. Examples include colour, hardness and smell and freezing, melting and boiling points.

A property of a group is more deeply bound to that group than a characteristic. A characteristic is descriptive, whereas properties are definitive. On the other hand, a property may be characteristic of a particular group, and a characteristic may be a property of a group. ... Define all material 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.
