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.Which of the following correctly describes a key difference between boiling and evaporation?
- A.Boiling occurs at all temperatures, while evaporation occurs only at a fixed temperature.
- B.Boiling is a slow process, while evaporation is rapid and occurs only under direct heating.
- C.Boiling requires the vapor pressure of the liquid to equal atmospheric pressure, while evaporation occurs at all pressures.
- D.Boiling and evaporation are identical processes with no differences in temperature or pressure conditions.
-
2.Heat energy is supplied at a constant rate to 400 g of ice at 0°C. The ice is converted into water at 0°C in 5 minutes. How much time will be required to raise the temperature of water from 0°C to 100°C? Specific latent heat of ice = 336 J g⁻¹, specific heat capacity of water = 4.2 J g⁻¹ K⁻¹.
- A.5 minutes and 36 seconds
- B.6 minutes and 15 seconds
- C.7 minutes and 20 seconds
- D.8 minutes and 45 seconds
-
3.A solid of mass 80 g and at 80°C melts completely to form liquid at 80°C by absorbing 640 J of heat energy. What is the specific latent heat of fusion of solid?
- A.8 J g⁻¹
- B.4 J g⁻¹
- C.2 J g⁻¹
- D.10 J g⁻¹
-
4.Why are hot water bottles particularly efficient for fomentation (heat therapy)?
- A.Water boils at a high temperature, providing intense heat.
- B.Water’s high specific heat capacity allows it to store and release large amounts of heat at moderate temperatures.
- C.Water evaporates quickly, enhancing heat transfer to the skin.
- D.Water’s low thermal conductivity ensures slow heat loss.
-
5.200 g of hot water at 80°C is added to 300 g of cold water at 10°C. What is the final temperature of the mixture? Consider the heat taken by the container to be negligible. [Specific heat capacity of water is 4200 J kg⁻¹°C⁻¹].
- A.30°C
- B.38°C
- C.45°C
- D.50°C
