Write the difference between ideal gas and real gas.

Answer
|
Ideal Gas
|
Real Gas
|
|
| (i) |
It obeys ideal gas equation, $\text{pV}=\mu\text{RT}$ at all temperatures and pressures
|
It does not obey, $\text{pV}=\mu\text{RT}$ at all values of temperature and pressure.
|
| (ii) |
The volume of the molecules of an ideal gas is zero.
|
The volume of the molecules of a real gas is non-zero.
|
| (iii) |
There is no intermolecular force between the molecules.
|
There is intermolecular force of attraction or repulsion depending on whether intermolecular separation is larger or small.
|
| (iv) |
There is no intermolecular potential energy (U) because intermolecular force (F) is zero.
|
Potential energy (U) does not equal to zero as intermolecular force (F) is not zero.
|
| (v) |
It has only kinetic energy.
|
It has both kinetic and potential energy.
|
| (vi) |
At absolute zero, the volume, pressure and internal energy become zero.
|
All real gases get liquified before reaching absolute zero. The internal energy of the liquified gas is not zero.
