question 111

Multiple Choice

A 50-g cube of ice, initially at 0.0 $\degree$ C, is dropped into 200 g of water in an 80-g aluminum container, both initially at 40 $\degree$ C. What is the final equilibrium temperature? (Specific heat for aluminum is 900 J/kg· $\degree$ C, the specific heat of water is 4186 J/kg· $\degree$ C, and L_f = 3.33 * 10⁵ J/kg.)

• A) 17.6\(\degree\)C
• B) 9.5\(\degree\)C
• C) 12.1\(\degree\)C
• D) 20.6\(\degree\)C
