Suppose a block of mass of lead of mass 0.4kg at temperature 95°C is dropped in 2kg of water originally at 20°C in a container.calculate the final temperature if no heat is lost to the container and environment;

Answer 1

heat lost by lead is gained by water

(mass Pb)(specific heat Pb)(temp change) = (mass H2O)(specific heat H2O)(temp change)
