Concept explainers
A cube of ice is taken from the freezer at -8.5°C and placed in an 85-g aluminum calorimeter filled with 310 g of water at room temperature of 20.0°C. The final situation is all water at 17.0°C. What was the mass of the ice cube?
Mass of ice cube
Answer to Problem 33P
Solution:
Explanation of Solution
Given Info:
Initial temperature is -8.5°C and placed in 85 g aluminum calorimeter with 310g of water at room temperature of 20°C. Final temperature is 17°C.
Formula used:
Heat for melting is given by
Where L is latent heat
Calculation:
Heat lost by water and aluminum at room temperature can be calculated as
The heat required for raising the temperature of ice melts the ice and increases the temperature to 17°C
