Free online mock test for Mechanical Properties of Fluids (ICSE Class 10 Physics) — 119 competency-based questions based on the latest CISCE 2027 syllabus, with instant marking. Try the samples below, then take the full test free.
What to expect: This mock test covers key concepts from the Mechanical Properties of Fluids 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.Beyond a limiting value of flow speed called the critical speed, steady flow loses steadiness and becomes:
- A.turbulent
- B.laminar
- C.stationary
- D.incompressible
-
2.Consider: (I) Surface tension has units N/m. (II) Surface energy has units J/m^2 (= N/m). (III) Surface tension of a liquid is independent of the area of the surface. Which are correct?
- A.I, II and III
- B.I and II only
- C.I and III only
- D.II and III only
-
3.According to Pascal's law, a change in pressure applied to an enclosed fluid is transmitted:
- A.undiminished to every point of the fluid and the walls of the container
- B.only to the bottom of the container
- C.with diminishing magnitude away from the point of application
- D.only in the vertical direction
-
4.A submarine window of area 0.04 m^2 is at depth 1000 m in sea water (rho = 1.03 x 10^3 kg/m^3, g = 10 m/s^2); the cabin is at sea-level atmospheric pressure. The net force on the window equals the gauge-pressure force, approximately:
- A.4.12 x 10^5 N
- B.104 x 10^5 N
- C.1.03 x 10^5 N
- D.4.12 x 10^3 N
-
5.Assertion (A): In the hydrostatic paradox, three vessels of different shapes connected at the bottom and filled with water show the same liquid level even though they hold different amounts of water. Reason (R): The pressure at a given depth in a liquid depends only on the height of the liquid column and not on the shape or cross-sectional area of the container.
- 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
