Waec Model Questions Vol1 2019 Chemistry Question 11
Practice objective / multiple choice question 11 from the 2019 Waec Model Questions Vol1 Chemistry examination.
A 500 g sample of ice at -10 °C is heated with a supply of 500 kJ of energy. The specific heat capacity of ice is 2.1 kJ kg⁻¹ K⁻¹, the latent heat of fusion of ice is 334 kJ kg⁻¹, the specific heat capacity of liquid water is 4.18 kJ kg⁻¹ K⁻¹ and the latent heat of vapourisation of water is 2260 kJ kg⁻¹. Assuming the system is open to the atmosphere so that water may boil, calculate the mass of water that remains in the liquid state after the energy has been supplied.
