Sample questions
-
1.The amount of heat required to convert 1 kg of ice at -10°C to steam at 100°C is 3,037,000 J. What is the specific latent heat of vaporisation of steam? Given: Specific heat capacity of ice = 2100 J kg⁻¹ K⁻¹; Specific heat capacity of water = 4200 J kg⁻¹ K⁻¹; Specific latent heat of ice = 336,000 J kg⁻¹.
- A.2.00 MJ kg⁻¹
- B.2.26 MJ kg⁻¹
- C.2.50 MJ kg⁻¹
- D.1.80 MJ kg⁻¹
-
2.Ice cream appears colder to the mouth than water at 0°C. Why?
- A.Ice cream has a lower temperature than water at 0°C.
- B.Ice cream absorbs latent heat from the mouth to melt, causing a greater cooling effect.
- C.Water at 0°C releases latent heat, warming the mouth slightly.
- D.Ice cream contains additives that enhance the cold sensation.
-
3.What is meant by the term 'specific heat capacity'?
- A.The amount of heat energy required to raise the temperature of unit mass of a substance through 1°C (or 1 K).
- B.The total heat energy contained in a substance at a given temperature.
- C.The temperature change produced by adding a fixed amount of heat to any substance.
- D.The heat energy needed to change the state of a unit mass of a substance without temperature change.

4.A molten metal of mass 150 g is kept at its melting point 800°C. When it is allowed to freeze at the same temperature, it gives out 75,000 J of heat energy. (a) What is the specific latent heat of the metal? (b) If the specific heat capacity of metal is 200 J kg⁻¹ K⁻¹, how much additional heat energy will the metal give out in cooling to -50 °C?
-
5.A hot iron ball of mass 0.2 kg is added into 0.5 kg of water at 10°C. The resulting temperature is 30°C. Calculate the temperature of hot ball. Specific heat capacity of iron = 336 J kg⁻¹ K⁻¹ and specific heat capacity of water = 4.2 × 10³ J kg⁻¹ K⁻¹.
