Problem

A 2.002.00-lb copper pipe (use 1 lb=453.6 g1\,\text{lb}=453.6\,\text{g}) cools from 150.0 ∘C150.0\,^{\circ}\text{C} to 25.0 ∘C25.0\,^{\circ}\text{C}. The specific heat capacity of copper is 0.385 J g−1 ∘C−10.385\,\text{J g}^{-1}\,^{\circ}\text{C}^{-1}. Calculate the amount of heat released in kilocalories  (1 kcal=4.184 kJ)\,(1\,\text{kcal}=4.184\,\text{kJ}).
