Option (b) 2 and 3 is correct.
Specific enthalpy and pressure
Are both intensive properties.
Explanation:-
{ Intensive properties are those that do not depend on the size of the system. Specific enthalpy is the enthalpy on a per gram basis. Since this value is normalized to the per gram basis it does not depend on the size of the system being measured. }
So, both are intensive properties.
So, both are intensive properties.

Intensive Properties in Thermodynamics
Intensive properties are those properties that do not depend on the size or amount of the system. They are unique to a substance and are independent of the amount of the substance present. Examples of intensive properties include temperature, pressure, density, specific heat, and specific enthalpy. In this question, we have to identify the intensive properties among the given options.
Options Analysis
1. Kinetic Energy: Kinetic energy is the energy possessed by an object due to its motion. It is a measure of the amount of work an object can do. It is not an intensive property as it depends on the size and amount of the system.
2. Specific Enthalpy: Enthalpy is the sum of internal energy and the product of pressure and volume. Specific enthalpy is the enthalpy per unit mass of a substance. It is an intensive property as it does not depend on the amount of the substance present.
3. Pressure: Pressure is the force per unit area exerted by a substance. It is an intensive property as it does not depend on the size or amount of the system.
4. Entropy: Entropy is the measure of the disorder or randomness of a system. It is an extensive property as it depends on the size and amount of the system.
Therefore, the intensive properties among the given options are:
- Specific Enthalpy
- Pressure
Hence, the correct answer is option B.

Kinetic energy is extensive property, enthalpy is extensive but specific enthapy is intensive pressure is intensive.. entropy is energy/unit temperature so it's extensive property....
