An ice-cube tray of negligible mass contains 2.5 kg of water at 25°C. How much heat must be removed to cool the water to 0°C and freeze it?

Jeffrey Jordon

Expert

m = 0.29 kg

initial temperature = 14 deg C

heat to bring the water to 0 deg C = mass*specific heat*change of temperature =

heat to freeze it completely = mass * latent heat of fusion =

a)So total heat removed injoules = 96860 + 16987.04 = 113847.04 J
