A piece of iron (Cp = 0.450 J/(gi°C)) that has a mass of 21.5 g and an initial temperature of 100.0°C is submerged in X g of water (Cp = 4.184 J/(gi°C)) at 20.0°C. The temperature of the system (iron and water) changes to 21.4°C. What is the value of X?
.041 g
80 g
132 g
574 g

cuanchi · Answer

The amount of energy release from the iron is equal to the energy by the x mass of water
you can use the equation
E=m Cp delta T
to calculate the E from iron and then use this value to calculate with the same formua but with the Cp of the water the m of water (x)
