A 5.00 kg piece of solid metal at an initial temperature T is placed with 1.00 kg of steam that is initially at 120.0°C, The steam is in an insulated container of negligible mass and no heat is exchanged with the surroundings. After thermal equilibrium is reached, there is 0.90 kg of steam and 0.10 kg of liquid water. Given that specific heat of metal cmetal900 J/kg K, and Csteam-2010 J/kg•K, cw=4190 J/kg K, and Lv=2.26x10 J/kg a) How much heat energy is given out by the 0.10 kg water? b) What was the initial temperature of the piece of metal?

Transcribed Image Text:. A 5.00 kg piece of solid metal at an initial temperature T is placed with 1.00 kg of steam
that is initially at 120.0°C. The steam is in an insulated container of negligible mass and
no heat is exchanged with the surroundings. After thermal equilibrium is reached, there is
0.90 kg of steam and 0.10 kg of liquid water.
Given that specific heat of metal cmetal=900 J/kg K, and Csteam-2010 J/kg•K, cw=
J/kg K, and Lv=2.26x10 J/kg
4190
