Chapter-13: Kinetic Theory |

1. A real gas behaves like an ideal gas if its –

- both pressure and temperature are high
- both pressure and temperature are low
- the pressure is high and the temperature is low
- the pressure is low and the temperature is high

2. Perfect gas equation –

- PV = RT
- PV = R/T
- PV = T/R
- PV = RV

3. Charles law –

- V/T = const
- VT = const
- PV = const
- V = 1/T

4. Boyle’s law const

- V/T = const
- PV = const
- VT = const
- P = 1/V

5. Degree of freedom for Monoatomie gas is –

- 3
- 5
- 8
- 7

6. Degree of freedom for Diatomic gas is –

- 3
- 8
- 7
- 5

7. The degree of freedom of a Triatemic gas is –

- 3
- 5
- 6
- 8

8. If the pressure and the volume of a certain quantity of ideal gas are doubled, then its temperature-

- become doubled
- become one – fourth
- remains constant
- become four times

9. If the pressure and the volume of a certain quality of ideal gas are hail, then its temperature –

- doubled
- becomes one fourth
- remains constant
- become four-time

10. The volume of a gas is increasing adiabatically. Its temperature –

- will increases
- will decreases
- will remains constant
- can increases or decreases
