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
