Is there anything wrong in this definition, if so, write the correct form: Intensive properties do not depend on the amount of matter present. Such properties include the melting point, boiling point, density, and ability to conduct electricity and to transfer energy as heat. Intensive properties are the same for a given substance regardless of how much of the substance is present.

Answer:

The definition and all examples are correctly mentioned only one mistake is spotted which is transfer of energy as heat included in Intensive Property which is wrong.

Explanation:

Intensive Property: Intensive properties are those properties which are Independent of the amount substance present.

For e.g. The melting point of ice on standard temperature & pressure is constant i.e. 0°C.

1 gram of ice will melt at 0°C so will be 1 kilogram ice. Hence melting point & similarly boiling point also is an Intensive Property.

before talking about Density let's understand Extensive properties.

Extensive Property: Extensive properties are those properties which are Dependent of the amount substance present.

for e.g. Volume, Weight, Mass, Length, Energy, Enthalpy, Entropy etc.

When One extensive divided by another extensive Property then perticular that property of substance is also intensive property.

Now we know that,

[tex] \sf Density = \frac{Mass}{volume} [/tex]

Where mass & volume both are extensive properties, hence density is an intensive property.

Ability to conduct electricity is called as Thermal Conductivity which is an intensive property.

The thermal conductivity of a perticular material does not change it varies material to material.

Transfer of energy as heat, let's have quick look at heat & temperature relation given by,

[tex]C = \frac{Q}{\Delta T} [/tex]

Where C is specific heat capacity which is an intensive property & specific heat is the ratio of added heat to the change in temperature & Heat is an Extensive property.
