ICSE Class 10 Thermodynamics — Mock Test (2027)
Free online mock test for Thermodynamics (ICSE Class 10 Physics) — 130 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 Thermodynamics 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.The Carnot cycle consists of:
- A.two isochoric processes connected by two isobaric processes
- B.two isothermal processes connected by two adiabatic processes
- C.four adiabatic processes
- D.two isobaric processes connected by two isothermal processes
-
2.A gas is taken adiabatically from equilibrium state A to state B, and 22.3 J of work is done ON the system. If instead the gas is taken from A to B by another process in which the net heat absorbed is 9.35 cal (1 cal = 4.19 J), the net work done BY the system in this second case is:
- A.About 16.5 J
- B.About 39.2 J
- C.About -22.3 J
- D.About 9.35 J
-
3.For a refrigerator, the Second Law of Thermodynamics says that the coefficient of performance can:
- A.be infinite
- B.never be infinite
- C.equal unity always
- D.be negative
-
4.Assertion (A): The internal energy of a given mass of gas depends only on its state, not on the path taken to reach that state. Reason (R): Internal energy is a thermodynamic state variable.
- 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
-
5.What amount of heat must be supplied to 2.0 x 10^-2 kg of nitrogen (molecular mass 28, so 0.714 mol) at room temperature to raise its temperature by 45 degrees C at constant pressure? (R = 8.3 J/mol/K, and for a diatomic gas Cp = (7/2)R)
- A.About 933 J
- B.About 533 J
- C.About 1400 J
- D.About 267 J
