Answer 1

too ice. Heat required from - 13.5°C to ooc ice. g=mst Immass=34179., sasp. heat g. 34.7 x 0.5x (0- (-13,5)) z5 cal/gm. = 243.225 Cal. I for ice Heat required from 0°c ice to o°c water: Latent heat so callam. 8= mL = 34.7 x 80 = 2776 Calory. [stor water Heat required from 0°c water to 100°c water.
