How much heat is required to change 50 g of ice at 0 oC into liquid water at 0 oC? Qmelt ice = cal 2) If 300 g of water initially at 25 oC released the amount of heat that you found in Part (1), what would its temperature be afterward? Tafter = oC 3)If you were to combine 50 g of liquid water at 0 oC with 300 g of the water at the temperature you found in Part...
