Question

Data: Part A: Assuming Perfectly Insulated System where QlostQgained 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 of water 25 C Initial temperature of Copper 90 C Final temperature of water for Copper + water 29 C 5. Heat Lost by Copper Q= (masscopper) (scopper)(Tfinal-Tinitial) -____ cal 6. Heat Gained by Water Q= (masswater) (swater)(Tfinal-Tinitial) _____ cal 7. Heat Lost to Surroundings or Calorimeter #5 - #6 (absolute value of change) _____ cal 8. Total heat generated from warm copper #6 + #7 _______ cal Part C: Heat of Fusion Find Hf water in the background section of your lab manual. Mass of water 25.5 g Mass of water + ice 50.5 g 9. Mass of ice _____ g 10. Heat required to melt ice Q= (massice) (Hf water) _____ cal
