The temperature at which real gases obey the ideal gas laws over a wide range of low pressure is called:
1. Critical temperature
2. Inversion temperature
3. Boyle temperature
4. Reduced temperature
What will happen to gas if it is adiabatically expanded at 600 K if its Boyle's temperature is 290 K?

However great the pressure, a gas cannot be liquified above its:
1. Boyle temperature

The temperature at which the second virial coefficient of real gas is zero is called:
1. Critical temperature
2. Triple point
3. Boiling point
4. Boyle's temperature
The correct order of temperature of a real gas is-
I. Boyle's temperature
II. Critical temperature
III. Inversion temperature
1. III > I > II
2. I > II > III
3. II > I > III
4. I > III > II
The excluded volume of a gas will be larger, if is:
1. small
2. large
3. equal to 1
4. less than unity
The critical temperature of a substance is:
1. The temperature above which the substance undergoes decomposition
2. The temperature above which a substance can exist only in a gaseous state
3. Boiling point of the substance
4. All are wrong
