a) Who doesn't like ice water to drink? Find the mass of ice that would be required to add to 475 mL of room temperature water (starting at 20 degrees Celsius) to result in the whole system ending with a temperature of 2 degrees Celsius. Know that the density of this water is 1000 g / L
b) Now, it's winter time! You lose power but still have your gas stove. Oh no! But, you 'really want a cup of tea. Find the amount of heat that would be required to turn 0.5 kilograms of that ice approximately 16 ouncesinto piping hot water that you could make tea with, at a temperature of 80 degrees C.
C)You have a hot plate that can deliver 900 Joules/second of heat to your system. How many minutes would it take for the ice to reach this tea-making temperature?
