Heat of Fusion and Vaporization practice 1. What is the equation for Heat of Fusion? 2. What is the equation for Heat of Vaporization? 3. What are the units for Heat of Fusion and Vaporization? 4. Explain the relation ship between Heat of Fusion(melting) and Heat of Solidification(freezing) 5. If 2083 Joules are used to melt 5.26g of aluminum, what is the Heat of Fusion? 6. If it releases -579 Joules to freeze a 10g sample of zinc, what is the Heat of Solidification? 7. How much energy does it take to boil a 125g sample of water? (Heat of Vaporization for water is 2259.4 J/g) 8. How much energy does it take to heat a 125g sample of steam from 100 to 140 Celsius? ( Specific heat of steam is 2.00 J/gC) 9. What is the mass of a sample of nickel, which melts after 3120 J of heat is absorbed? (Heat of Fusion of nickel is 298 J/g) 10. Calculate the total energy lost when a 100g sample of water vapor goes from 140 Celsius to -10 Celsius. The sample will condense and freeze during this process. Condensation point = 100 degrees Freezing point= 0 degrees Heat of Condensation= -2259.4 J/g Heat of solidification= -334.7 J/g Specific Heat of vapor= 2.00 J/gC Specific Heat liquid= 4.18 J/gC Specific Heat of Solid= 2.11 J/gC
