What to expect: This mock test covers key concepts from the Kinetic Theory of Gases chapter — including application-based and competency-focused questions aligned with how ICSE actually sets the paper.
Tip: Attempt without notes first to identify gaps, then review explanations for any wrong answers. Retake after a few days for best retention.
Sample questions
-
1.Real gases approach ideal gas behaviour at
- A.low pressures and high temperatures
- B.high pressures and low temperatures
- C.low pressures and low temperatures
- D.high pressures and high temperatures
-
2.In deriving the gas pressure, because the gas is isotropic with no preferred direction, the average of vx^2 equals
- A.(1/3) vbar^2
- B.(1/2) vbar^2
- C.vbar^2
- D.(2/3) vbar^2
-
3.The Boltzmann constant kB is related to the gas constant R and Avogadro number NA by
- A.kB = R / NA
- B.kB = R x NA
- C.kB = NA / R
- D.kB = R + NA
-
4.A vessel contains neon (monatomic) and oxygen (diatomic) with the ratio of their partial pressures equal to 3:2. The ratio of the number of molecules of neon to oxygen (N1:N2) is (Example 12.4):
- A.3:2
- B.2:3
- C.9:4
- D.1:1
-
5.Assertion (A): In the kinetic theory the collisions of molecules among themselves and with the walls are taken to be elastic. Reason (R): This implies that the total kinetic energy of the molecules is conserved in the collisions.
- A.Both A and R are true and R is the correct explanation of A
- B.Both A and R are true but R is NOT the correct explanation of A
- C.A is true but R is false
- D.A is false but R is true
