Sample questions
-
1.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.
-
2.(a) Calculate the heat capacity of a copper vessel of mass 150 g if the specific heat capacity of copper is 410 J kg⁻¹ K⁻¹. (b) How much heat energy will be required to increase the temperature of the vessel in part (a) from 25°C to 35°C?
-
3.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.
-
4.How much heat energy is released when 5 g of water at 20°C changes to ice at 0°C? [Specific heat capacity of water = 4.2 J g⁻¹ °C⁻¹, Specific latent heat of fusion of ice = 336 J g⁻¹]
-
5.The specific heat capacity of a substance
- a.changes with rise or fall in temperature.
- b.is a constant quantity for a given substance
- c.changes with the mass of given substance.
- d.changes with the area or volume of substance.
