2. A 10 g ice cube, initially at 0 ºC, is melted in 100 g of water that was initially 20°C. After the ice has melted, the equilibrium temperature is 10.93 ºC. Calculate: a. The total heat lost by the water (the specific heat for water is 4.186 J/g/K). Click here to enter text. 3. b. C. The heat gained by the ice cube after it melts (the specific heat for ice is 2.093 J/g/K). Click here to enter text. The heat it took to melt the ice (Hint: it takes 334 J of heat energy to melt 1 g of ice). Click here to enter text. Inside a calorimeter is 100 g of water at 39.8°C. A 10 g object at 50°C is placed inside of a calorimeter. When equilibrium has been reached the new temperature of the water and metal object is 40°C. What type of metal is the object made from?
