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

[su_spoiler title=”View Answer ” style=”fancy”]the pressure is low and the temperature is high[/su_spoiler]

2. Perfect gas equation –

  • PV = RT
  • PV = R/T
  • PV = T/R
  • PV = RV

[su_spoiler title=”View Answer ” style=”fancy”]PV = RT[/su_spoiler]

3. Charles law –

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

[su_spoiler title=”View Answer ” style=”fancy”]PV = const[/su_spoiler]

4. Boyle’s law const

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

[su_spoiler title=”View Answer ” style=”fancy”]PV = const[/su_spoiler]

5. Degree of freedom for Monoatomie gas is –

  • 3
  • 5
  • 8
  • 7

[su_spoiler title=”View Answer ” style=”fancy”]3[/su_spoiler]

6. Degree of freedom for Diatomic gas is –

  • 3
  • 8
  • 7
  • 5

[su_spoiler title=”View Answer ” style=”fancy”]5[/su_spoiler]

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

  • 3
  • 5
  • 6
  • 8

[su_spoiler title=”View Answer ” style=”fancy”]6[/su_spoiler]

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

[su_spoiler title=”View Answer ” style=”fancy”]become four times[/su_spoiler]

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

[su_spoiler title=”View Answer ” style=”fancy”]becomes one fourth[/su_spoiler]

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

  • will increases
  • will decreases
  • will remains constant
  • can increases or decreases

[su_spoiler title=”View Answer ” style=”fancy”]will decreases[/su_spoiler]
