The compressibility factor for nitrogen at 330 K and 800 atm is 1.90 and at 570 K and 200 atm is 1.10. A certain mass of occupies a volume of at 330 K and 800 atm. Calculate volume occupied by same quantity of gas at 570 K and 200 atm:
1. 1 L
2. 2 L
3. 3 L
4. 4 L

Pressure remaining the same, the volume of a given mass of an ideal gas increase for every degree centigrade rise in temperature by definite fraction of its volume at:
1.
2. Its critical temperature
3. Absolute zero
4. Its Boyle temperature
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
The excluded volume of a gas will be larger, if is:
1. small
2. large
3. equal to 1
4. less than unity
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 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
However great the pressure, a gas cannot be liquified above its:
1. Boyle temperature
2. Inversion temperature
3. Critical temperature
4. Room temperature
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
