Solved: An open container holds 0.550 kg of ice at - 15.0o
Chapter 17, Problem 50E(choose chapter or problem)
An open container holds 0.550 kg of ice at - 15.0\(^\circ\)C. The mass of the container can be ignored. Heat is supplied to the container at the constant rate of 800.0 J/min for 500.0 min. (a) After how many minutes does the ice start to melt? (b) After how many minutes, from the time when the heating is first started, does the temperature begin to rise above 0.0\(^\circ\)C? (c) Plot a curve showing the temperature as a function of the elapsed time.
