Free online mock test for Heat (ICSE Class 10 Physics) — 20 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 Heat 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. 1.What is the S.I. unit of heat?
    • A.calorie
    • B.joule (J)
    • C.watt
    • D.kelvin
  2. 2.The specific heat capacity of substance A is 3800 Jkg⁻¹K⁻¹ and that of substance B is 400 Jkg⁻¹K⁻¹. Which substance is a better conductor of heat and why?
    • A.Substance A, because it requires more heat to raise its temperature.
    • B.Substance B, because it requires less heat to raise its temperature.
    • C.Substance A, because it retains heat longer.
    • D.Substance B, because it has a higher melting point.
  3. 3.Which of the following is the S.I. unit of heat?
    • A.calorie
    • B.joule (J)
    • C.kelvin (K)
    • D.watt (W)
  4. 4.What is the approximate value of the specific heat capacity of water in S.I. unit?
    • A.420 J kg⁻¹ K⁻¹
    • B.4200 J kg⁻¹ K⁻¹
    • C.42000 J kg⁻¹ K⁻¹
    • D.4.2 J kg⁻¹ K⁻¹
  5. 5.Water boils at $120^{\circ}\mathrm{C}$ in a pressure cooker. Why does this occur?
    • A.The pressure cooker reduces the atmospheric pressure, allowing water to boil at a higher temperature.
    • B.The sealed environment increases the pressure inside, raising the boiling point of water above $100^{\circ}\mathrm{C}$.
    • C.The pressure cooker heats water more efficiently, directly increasing its temperature beyond $100^{\circ}\mathrm{C}$.
    • D.The boiling point of water is naturally $120^{\circ}\mathrm{C}$ under all conditions due to its molecular structure.
