An open container holds 0.550 kg of ice at - 15.0 degree celsius. The mass of the container can be ignored. Heat is supplied to the container at the constant rate of 800 J/min for 500 min .
Part A After how many minutes does the ice start to melt? = 21.7
Part B After how many minutes, from the time when the heating is first started, does the temperature begin to rise above 0 ?=252
Part C Plot a curve showing the temperature as a function of the elapsed time.
