Answer to Question #124381 in General Chemistry for Liv L Palmer

Question

A metal cube with a mass of 55grams at temperature of 85°C is immersed in 150grams of water at temperature of 20°C. The metal and water then reach a final temperature of 23°C. What is the specific heat of the metal?

Specific heat of water, which is 4.184 J/gC.

Answer 1

Let the specific heat of the metal be s J/gC

Heat lost by metal = Heat gained by water

55 x s x (85-23) = 150 x 4.184 x (23-20)

s = 0.5521 J/gc (Answer)
