You are a blacksmith and have been working with 11.0 kg of steel. When you are finished shaping it, the steel is at a temperature of 475°C. To cool it off, you drop it into a bucket containing 6.0 kg of water at 70°C. How much of this water is converted to steam? Assume the steel, the water, and the steam all have the same final temperature.

_______ kg

Solution

Q(steel)[475*C to 100*C] = Q(water)[70*C to 100*C] + Q(water)[100*C water to 100*C Steam]

11 * 545 * (475 - 100) = 6 * 4187 * (100 - 70) + (m * 2270000 )

11 * 545 * 375 = 6 * 4187 * 30 + m * 2270000

m = 0.66 Kg
