question 4

Multiple Choice

A 200-g metal container, insulated on the outside, holds 100 g of water in thermal equilibrium at 22.00°C. A 21-g ice cube, at the melting point, is dropped into the water, and when thermal equilibrium is reached the temperature is 15.00°C. Assume there is no heat exchange with the surroundings. For water, the specific heat is 4190 J/kg · K and the heat of fusion is 3.34 × 10⁵ J/kg. The specific heat for the metal is closest to

• A) 3850 J/kg ∙ K.
• B) 2730 J/kg ∙ K.
• C) 4450 J/kg ∙ K.
• D) 4950 J/kg ∙ K.
• E) 5450 J/kg ∙ K.
