QUESTION 1 Which of the following will affect the amount of energy it takes to change the temperature of a solid substance by 10 °C? the atmospheric pressure the initial temperature of the substance the specific heat capacity of the substance the amount (mass) of the substance you have QUESTION 2 A piece of metal A and a piece of metal B of the same mass and at the same temperature of 80°C are dropped into separate beakers each containing 100.0 g of water at room temperature. Once they equilibrate, you find that the beaker with the sample of metal A is warmer than the beaker with the sample of metal B. Which metal has the larger specific heat capacity? Metal A Metal B QUESTION 3 If the enthalpies of formation of carbon dioxide and water are -393.509 k/mol and -285.83 k/mol respectively, what is the enthalpy of formation of C10H8(s) in kJ/mol? C10H8(s) + 1 202(g) â 1 0CO2(g) + 4H20 (I) ì¨ o--51 56.1 kj
