Properties of System 

All macroscopic properties of a system irrespective of the fact whether they are state variable or not are divided into two types: 

1. Intensive Properties

Such properties remain the same on any division in a system that is, do not depend upon the amount of substance present in the system. 

Example: Temperature, pressure, concentration, density, viscosity, surface tension, specific heat, refractive index, pH, EMF of dry cell, vapour pressure dipole moment etc.

 

2. Extensive Properties 

Such properties depend upon the amount of substance that is, their values are different in the divided system than in the entire system 

Example, Mass, volume, energy, work, internal energy, entropy, enthalpy, heat capacity, length.

 

An extensive property can be made intensive specifying it In-unit amount of matter.

\mathrm{Example, Density \approx\left(\frac{\text { Mass }}{\text { Volume }}\right)}


Therefore we can say enthalpy depends upon the quantity of substance.
Hence, option number (1) is correct.
