Is Enthalpy Intensive Or Extensive. If the property is unchanged by altering the sample size, it's an intensive property. The energy or enthalpy of an object clearly depends on the number of particles or atoms in the object.

Other extensive properties include mass, volume, energy, work, internal energy, entropy etc. If the property is unchanged by altering the sample size, it's an intensive property. The energy or enthalpy of an object clearly depends on the number of particles or atoms in the object. Web enthalpy is an extensive property as its value depends on the amount of substance present in the system. As intensive properties, the specific enthalpy h = h / m is referenced to a unit of mass m of the system, and the molar enthalpy h m is h / n, where n is the number of moles. Engineers use the specific enthalpy in thermodynamic analysis more than the enthalpy itself. However, it is also an intensive property when quoted in kj/mol or kj/kg. If this doubles the property (e.g., twice the mass, twice as long), it's an extensive property. You take the extensive property and devide it by the objects mass. Web the specific heat capacity is intensive, and does not depend on the quantity, but the heat capacity is extensive, so two grams of liquid water have twice the heat capacitance of 1 gram, but the specific heat capacity, the heat capacity per gram, is.
Web one easy way to tell whether a physical property is intensive or extensive is to take two identical samples of a substance and put them together. Web enthalpy is therefore an extensive property. Web extensive quantities are those that depend upon the amount of material. It is proportional to the size of the system (for homogeneous systems). Web density is therefore an intensive property. Intensive properties do not depend on the amount present. Web one easy way to tell whether a physical property is intensive or extensive is to take two identical samples of a substance and put them together. So, one can make those extensive properties into intensive ones. Web enthalpy is an extensive property as its value depends on the amount of substance present in the system. They include colour, melting point, boiling point, electrical conductivity, and physical state at a given temperature. Other extensive properties include mass, volume, energy, work, internal energy, entropy etc.
