Sample questions
-
1.Find the time taken by a 500 W heater to raise the temperature of 50 kg of material of specific heat capacity 960 J kg⁻¹ K⁻¹ from 18°C to 38°C. Assume that all the heat energy supplied by the heater is given to the material.
- A.16 min

3.Steam at 100°C is passed over 1000 g of ice at 0°C. After some time, 600 g of ice at 0°C is left and 450 g of water at 0°C is formed. What is the specific latent heat of vaporisation of steam? (Given: specific heat capacity of water = 4200 J/kg°C and specific latent heat of fusion of ice = 336000 J/kg).
- A.1134000 J/kg
- B.2268000 J/kg
- C.3360000 J/kg
- D.4536000 J/kg
-
4.A copper vessel of mass 100 g contains 150 g of water at 50°C. How much ice is needed to cool it to 5°C? Given: Specific heat capacity of copper = 0.4 J/g°C; Specific heat capacity of water = 4.2 J/g°C; Specific latent heat of fusion of ice = 336 J/g.
-
5.What mass of ice at 0°C must be added to 2.1 kg of water to cool it from 75°C to 25°C? (Given: Specific heat capacity of water = 4.2 J g⁻¹ °C⁻¹, Specific latent heat of ice = 336 J g⁻¹)
- A.500 g
- B.1000 g
- C.1500 g
- D.2000 g
