Question
what heat change takes place when an equilibrium system of 2.0 grams of ice and 3.0 grams of water at 0 degrees Celsius is converted entirely to ice at 0 degrees Celsius? (heat of fusion of ice =334 J/g) what heat change takes place when an equilibrium system of 2.0 grams of ice and 3.0 grams of water at 0 degrees Celsius is converted entirely to ice at 0 degrees Celsius? (heat of fusion of ice =334 J/g) what heat change takes place when an equilibrium system of 2.0 grams of ice and 3.0 grams of water at 0 degrees Celsius is converted entirely to ice at 0 degrees Celsius? (heat of fusion of ice =334 J/g)Explanation / Answer
It is said that entire mixture ( ice + water ) has to be converted to ice at 0 0C.
So already we have 2.0 grams of ice at 0 0C. So only 3.0 grams of water at 0 0C has to be converted to ice at 0 0C.
Heat that is to be removed i.e., latent heat of fusion = m Lf = 3.0 * 334 = 1002 J = 1.002 kJ.
