Answer to Question #76843 in Molecular Physics | Thermodynamics for Alika

Question

A block of copper of mass 980g at a temperature of 120 degrees Celsius was placed in a beaker if water containing 250cm3 of water. If the water is at 12 degrees Celsius, explain what happens to the water with calculation for evidence.
Shc of water= 4200 J kg-1 K-1 Latent heat of fusion (Lf) = 2,340,000 J kg-1 shc of copper = 450 J kg-1 K-1

Answer 1

qreleased by metal = qabsorbed by water
-(mCpT)metal = (mCpT)water
-(26 g)Cp(32.5°C - 98.0°C) = (150 g)(4.18 J/g°C)(32.5°C - 26.0°C)
Cp(metal) = 2.39 J/g°C
