Question

A 0.01 kg ingot of metal is heated to 200°C and then dropped into a beaker containing water at 20°C , if the final equilibrium temperature of the system is 40°C then the heat lost by metal is ____. (Given specific heat of metal is 450J/kg°C)

Answer 1

Answer:

Mass of the metal, m = 0.20 kg = 200 g Initial temperature of the metal, T1 = 150 o CFinal temperature of the metal, T2 = 40 o CCalorimeter has water equivalent
