Question

14 The specific heat values of four different substances are given Which substance would heat up the fastest a 1 02 x 10 2 J g C 9 18 x 104 J g C b 15 If object A has a higher temperature than object B then object A c 0 918 J g C d 1 02 J g C a contains more energy as heat than object B b contains less energy as heat than object B c contains the same amount of energy as heat as object B d may contain more less or the same amount of energy as heat as object B 16 A chemical reaction is exothermic when AH is c positive d negative a b zero constant 17 The term that describes disorder in a system is enthalpy c free energy entropy d heat of reaction a b 18 One mole of benzene vapor is cooled to its boiling point The amount of energy released by the benzene as it completely condenses is its enthalpy of fusion entropy of fusion C enthalpy of vaporization d entropy of vaporization 19 Which statement is true for the combustion of ethanol C H5OH 1 302 g 2CO2 g 3H O 1 AH 1370 kJ The enthalpy change would be the same is gaseous water were produced b The potential energy of the products is less than the potential energy of the reactants The potential energy of the products is higher than the potential energy of the reactants The reaction is endothermic a a b C d
