Chapter 5, Problem 47PS
An “ice calorimeter” can be used to determine the specific heat capacity of a metal. A piece of hot metal is dropped onto a weighed quantity of ice. The energy transferred from the metal to the ice can be determined from the amount of ice melted. Suppose you heated a 50.0-g piece of silver to 99.8 °C and then dropped it onto ice. When the metal’s temperature had dropped to 0.0 °C. it is found that 3.54 g of ice had melted. What is the specific heat capacity of silver?
