Steel Steam
February 1st, 2010
physics problem asking to find how much water is converted to steam after hot steel in placed in it. help!?
you are a blacksmith and have been working with 12 kg of steel. when you are finished shaping it, the steel is at a temperature of 400 degrees celsius. to cool it off, you drop it into a bucket containing 5.0 kg of water at 50 degrees celsius. how much of the water is converted to steam? assume the steel, the water, and the steam all have the same final temperature.
please show work if possible. thanks so much! i appreciate it everyone!
Let m kg of water is converted to steam.
=>Q(steel)[400*C to 100*C] = Q(water)[50*C to 100*C] + Q(water)[100*C water to 100*C Steam]
=> 12 x 452 x 300 = 5 x 4187 x 50 + m x 2270000
=> 1627200 – 1046750 = m x 2270
=> 580450 = 2270000 x m
=>m = 580450/2270000 =0.26 Kg
