A 1 kg blоck оf ice аt 0.00°C is thrоwn into а swimming pool аt 22.0°C and melts (assume all the melted ice becomes water at exactly 0°C). If the pool remains at 22.0°C, calculate the change in entropy of the ice. Calculate the solution in J/K. Type only the number part of the answer - do not include units. Include negative signs where appropriate. specific heats.JPGLatent Heat.JPG
