Here we discussed the extensive property and intensive property in thermodynamics with the list of examples, but before the discussion about intensive and extensive properties, we have a little bit of knowledge about thermodynamics. Thermodynamics is derived from two words therm means “heat” and dynamics mean “motion”. Thermodynamics means heat in motion.

System + Surrounding = Universe

The universe is a combination of systems and surroundings. The part of the universe under investigation is called a system and anything expect system is called a surrounding.

Surrounding = Universe – System

In thermodynamics, the main observation is a system but the question is how a system is defined without surroundings? The system cannot be defined without surroundings. So we can say that there is a boundary between the system and its surroundings.

## Difference Between Intensive property and Extensive Property?

Any system has two types of properties, extensive property and intensive property.

### What is meant by Extensive Property?

• Extensive property depends on the amount of matter.
• It depends on the size of sample.
• Example of extensive property is mass, volume, number of moles, heat capacity (heat capacity is the amount of heat required to rise the temperature of a body by 1°C), Energy (work, heat, enthalpy, entropy, gibbs free energy, internal energy).

### What is meant by Intensive Property?

• Intensive property does not depends on the amount of matter.
• It does not depend upon size of sample.
• Example of intensive property is temperature, pressure, density, refractive index, viscosity, specific heat capacity, concentration terms (molarity, molality, normality, mole fraction etc).

`"If the ratio of two extensive property then the property is intensive"`

Extensive / Extensive = Intensive

### Is Molarity is Intensive or Extensive?

Molarity is the ratio of number of moles and volume.

Molarity = no. of moles / volume

Both the no. of moles and volume is an extensive property so molarity is an intensive property.

Molarity = no. of moles / volume = extensive / extensive = Intensive property

### Is Molar Entropy is Intensive or Extensive?

Molar entropy is the entropy upon no. of moles.

Molar entropy = Entropy / moles

As we know that entropy and number of moles is the entensive property.

Molar entropy = Entropy / moles = Extensive / Extensive = Intensive propery

So, Molar entropy is the intensive property.

### Is Molar Internal Energy is Intensive or Extensive?

Molar internal energy is the internal energy upon no. of moles.

Molar internal energy = Internal energy / moles

As we know that internal energy and number of moles is the entensive property.

Molar internal energy = Internal energy / moles = Extensive / Extensive = Intensive propery

So, Molar internal energy is the intensive property.

### Is pH Intensive or Extensive?

pH = -log [H+]

pH is the negative log concentration of H+ and as we know that concentration is the intensive property so pH is the intensive property.

### Which of the following is the Extensive Property?

a) Specific heat capacity

b) Gibbs free energy

c) Electromotive force

d) Dielectric constant
