Data: Part A: Assuming Perfectly Insulated System where QlostQgained Round all values to 1 decimal place (don’t worry about significant figures) Find Swater and Scopper in the background section of your lab manual. Specific heat of water is (1.000 cal/g degree celsius). Specific heat of copper is (0.092 cal/g degree celsius). Heat of fusion of water is (80.0 cal/g degree celsius). Mass of Copper 20 g Volume of water (assume density of 1g/mL to get mass) 25 mL Initial temperature...

To cool her 0.200 kg cup of 75.0 C hot chocolate (mostly water), Heidi drops a 29,.97 g ice cube at 0 C into her insulated cup. After the ice cube melts, the temperature of the hot chocolate comes down to 54.8 C. a. How much energy was lost by the hot chocolate? The specific heat capacity of water is 1 cal/g C b. How much energy was gained by the ice cube just to melt to 0 C water?...

What is the mass of ice (in g) at 0 °C that can be completely melted into liquid water at 0°C by a 119 g aluminum block at temperature 112 °C? Assume the aluminum block can melt the ice until its temperature drops to 0 °C. The heat capacity of aluminum is 0.903 J g-1 °C-1 and the heat of fusion of water is 6.02 kJ mol-1. Express your answer to 3 significant figures.
