I)Heat of fusion of ice at 0°C and 1atmosphere is 6.01 kJ mol" and heat ofevaporation of water at 100 °C is 40.7 kJmol-1. Calculate the enthalpy change forthe conversion of 1 mole of ice at 0°C intovapour at 100°C. Heat capacity of wateris 4.184 JK-1 mol1. |

Answer» Answer: heat RELEASED to cool 500g water from 20 ∘ C to 0 ∘ C. q=msΔT =500×4.18×20=41800J =41.8kJ Number of MOLES of water(ICE) that will melt to absorb 41.8kJ= 6.02 41.8
