Section 15-10: Energy and Change of Temperature: Specific Heat See Table 155 for specific heat values. 75. Samples of two different metals, A and B, have the same mass. Both samples absorb the same amount of energy. The temperature of A increases by 11C, and the sample of B increases by 13C. Which metal has the higher specific heat? Explain your reasoning. 76. In the laboratory a student finds that it takes 27.6 joules to increase the temperature of 10.7g of gaseous xenon from 22.7 to 39.9 degrees Celsius. What is the measured specific heat of xenon? 77. Find the quantity of energy released (in joules) as 467g of zinc cools from 68C to 31C. 78. How much energy is required to raise the temperature of 10.4g of solid magnesium from 22.4C to 39.5C ? 79. How much energy (kJ) is released when 2.30kg of gold is cooled from 88C to 22C ? 80. What is the energy change when the temperature of 10.1g of solid silver is decreased from 38.1C to 23.6C ? 81. The mass of a handful of copper coins is 144g. The coins are at a temperature of 33C. If they lose 1.47kJ when they are tossed in a fountain and drop to the fountain's water temperature, what is that temperature? A U.S. penny was made of pure copper until 1857. Today's penny is 2.5% copper and 97.5% zinc. 82. A sample of solid sulfur is heated with an electrical coil. If 105J of energy is added to a 12.4g sample initially at 24.4C, what is the final temperature of the sulfur
