In a thermally insulated container was a mixture of ice and water. Then we have put a immersion heater ( P=400W). We started measure time and at the end of every minute we writed down the heat od mixture. First two minutes the heat wasn't changing, at the end of third it raised about 2°C, at the end of fourth it raised about 8°C, t the end of fifth raised about 8°C, and so on, each by an additional 8°C. Task: a) How much ice and how much water was in a container in the beginning? (my answer: mass of water: 0,515kg, mass of ice: 0,199kg) b) How long did it takes to ice, untill it melted? (my answer: 2:45min) c) How long did it takes untill the water started to boil? And how long did it takes untill the half of water did evaporate? (my answer: 14:25min and 48:2min) Thanks in advance!!
