1. (A) The following gives the calorimetric values for water at various phases: Latent heat of vaporization for water: 22.6 E5 J/kg Specific heat capacity for liquid water: 4,186 J/kgC Specific heat capacity for steam is 2,080 J/kgC A 19-g sample of liquid water at 80.0 C is converted to steam at 115 C. Using the values from the table above, calculate the heat required for that conversion. (B) Use the following calorimetric values to answer the question: The specific heat capacity of water is 4,186 J/kgC. The specific heat capacity for copper is 387 J/kgC. A 75-g copper ball at 94 C was dropped into 50. g of water. The final temperature of the water and the ball was 52 C. What was the initial temperature of the water? (C) Use the following calorimetric values to answer the question: The specific heat capacity of water is 4186 J/kgC. The specific heat capacity for aluminum is 899 J/kgC. A 140-g aluminum ball at 80. C was dropped into a beaker of water at 10. C. The final temperature of the water and the ball was 35 C. What was the mass of the water? (D) While riding his bicycle, Jans does 7.5 E7 J of work and gives off 4.3 E7 J of heat. What is the change in Jan's internal energy? + 3.2 E 7 J 3.2 E 7 J 11.8 E 7 J +11.8 E 7 J
