the following question. Use 9.8 for G in case. Answer them step by step and in order and include the unit as well for each one that needs. This is the homework for week 11. It includes multiple problems related to thermodynamics. 1. 60L of gasoline at 15degrees C is warmed to 36degrees C. What is the new volume? 2. A 0.481kg block of a pure material is heated from 20degrees C to 65degrees C by the addition of 5.238kJ of energy. Calculate its specific heat. 3. A bag containing 0degree C ice is much more effective in absorbing energy that one containing the same amount of 0degree C water. How much heat transfer is required to first melt 0.96kg of 0degree C ice and then raise its temperature to 22.7degrees C. 4. A bowl is filled with 0.175kg of 60C soup (mostly water) that is stirred with a 20C silver spoon of mass 0.04kg. The spoon slips into the soup. What equilibrium temperature will be reached if the spoon is allowed to remain in the soup and no heat is lost to the outside air? (cspoon = 240 J/kgC). Assume the temperature of the bowl does not change. 5. A chef is kneading dough in his 21C kitchen. The dough is placed on a 0.4mx0.6m aluminum cookie sheet. If the oven temperature is 177C, how much does the cookie sheet expand in area while it is in the oven? 6. A man is knitting his wife a sweater in his 18C air-conditioned living room with 0.3m long aluminum knitting needles when he decides to knit outside in the 27C air. How much will the knitting needles expend when taken outside? 7. An aluminum calorimeter with a mass of 90g contains 245g of water. The calorimeter and water are in thermal equilibrium at 10C. Two metallic blocks are placed into the water. One is a 49g piece of aluminum at 70C. The other has a mass of 460g and is originally at a temperature of 100C. The entire system stabilizes at a final temperature of 20C. Determine the specific heat of the unknown sample. 8. An aluminum rod is 30cm long at 33C and has a mass of 330g. If 13,000 J of energy is added to the rod by heat, what is the change in length of the rod? Do not use scientific notation and enter your answer in m. 9. Convert the following temperature. Round to the nearest whole number and do not include units in your entry. 10. Convert the following temperature. Round to the nearest whole number and do not include units in your entry. 97.4F to K 11. Convert the following temperature. Round to the nearest whole number and do not include units in your entry. 523K to F 12. Frost damage to most plants occurs at temperatures of 28degrees F or lower. What is this temperature on the Kelvin scale? 13. How large an expansion gap should be left between steel railroad rails if they may reach a maximum temperature 35degrees C greater than when they were laid? Their original length is 10m. 14. How much heat transfer (in kilocalories) is required to thaw a 0.45kg package of frozen vegetables originally at 0degrees C if their heat of fusion is the same as that of water? 15. How much heat transfer is required to raise the temperature of a 0.75kg aluminum pot containing 2.5kg of water from 30degree C to the boiling point and then boil away 0.75kg of water? 16. How much taller does the Eiffel Tower become at the end of a day when the temperature has increased by 15degrees C? It's original height is 321m and it is made of (mostly) steel. 17. Hypothermia can occur if the body temperature drops to 35C, although people have been known to survive much lower temperatures. In 1985 a 2year old child was found with a body temperature of 16C. If the child's mass was 10kg, how much heat did his body lose, assuming his normal body temperature is 37C (chuman body = 3470 J/kg C). 18. The bridge is a 512 m long steel arch. How much will its length change between temperature extremes -17C and 36C? 19. The height of the Washington Monument is measured to be 170m on a day when the temperature is 35degrees C. What will its height be on a day when the temperature falls to -10degrees C? Although the monument is made of limestone, assume it has the same thermal coefficient of expansion as concrete. 20. The surface temperature of the Sun is about 5750K. What is this temperature on the Fahrenheit scale
