1. विस्तीर्ण और गहन गुण में अन्तर स्पष्ट कीजिये। Differentiate between Intensive and Extensis
Answers
Answer:
Explanation:
Intensive properties do not depend on the quantity of matter. Examples include density, state of matter, and temperature. Extensive properties do depend on sample size. Examples include volume, mass, and size.
Answer:
Intensive properties: They are the properties of the system which are the independent of the quantity of matter present in the system.
- Temperature
- Pressure
- Refractive index
- Viscosity
- Specific heat
- Density
- Concentration
- Freezing point
- Boiling point
Intensive properties are not additive in nature. If we take water in a beaker at 25°C and double its volume. The temperature of water remains same. Therefore Intensive properties are not additive in nature.
Extensive properties: The properties of the system which depend upon the quantity of matter present in the system.
- Volume
- Mass
- Length
- Enthalpy
- Gibbs free energy
- Entropy
- Heat capacity
- Internal energy
Extensive properties are additive in nature. If we double the volume of water, its mass will be doubled as well.
Extensive property will become intensive property, if we fixed the amount of substance. For example: molar volume, molar enthalpy, molar entropy all are intensive properties.
