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.S.I. unit of thermal capacity is:
- A.J kg⁻¹
- B.J K⁻¹
- C.kJ kg⁻¹
- D.cal °C⁻¹
-
2.State the effect of the presence of an impurity on the melting point of ice and identify a practical application of this phenomenon.
- A.The melting point of ice increases; used in refrigeration to keep ice solid longer.
- B.The melting point of ice decreases; used to melt ice on roads by spreading salt.
- C.The melting point of ice remains unchanged; used to purify water by freezing.
- D.The melting point of ice fluctuates randomly; used in scientific experiments only.
-
3.$1.6\,\mathrm{kg}$ of boiling water at $100^{\circ}\mathrm{C}$ is poured into $2\,\mathrm{kg}$ of crushed ice at $0^{\circ}\mathrm{C}$, such that final temperature recorded is $0^{\circ}\mathrm{C}$. Calculate the specific latent heat of fusion of ice.
-
4.A solid of mass $150\,\mathrm{g}$ at $200^{\circ}\mathrm{C}$ is placed in $0.4\,\mathrm{kg}$ of water at $20^{\circ}\mathrm{C}$ till a constant temperature is attained. If the S.H.C. of the solid is $0.5\,\mathrm{Jg}^{-1}\,\mathrm{K}^{-1}$, find the resulting temperature of the mixture.
-
5.200 g of hot water at 80°C is added to 300 g of cold water at 10°C. Neglecting the heat taken by the container, calculate the final temperature of the mixture of water. Specific heat capacity of water = 4200 J kg⁻¹ K⁻¹.
