A reaction in a container releases 120 kJ of heat to the surroundings and 50 kJ of work is done on the system by the surroundings. Calculate the change of internal energy, AU, of the system. O a. AU = +70 kJ O b. AU=-70 kJ C. AU = 0 kJ (no change). O d. AU +170 kJ O e. AU = -170 kJ A 10 g metal bar is heated to 498 K immediately before it is immersed into a beaker containing 100 mL of water which has an initial measured temperature of 298 K (the beaker is surrounded by polystyrene to minimize any loss of heat). After immersion of the hot bar, the temperature of the water increases to 320 K. A diagram of this experiment is shown below: Calculate the amount of heat that is transferred from the bar into the water. (density of water = 1.00 g mL and specific heat capacity of water = 4.18 J K-1g-1). O a. +9.20 kJ O b. +4.18 kJ O c. –9.20 kJ O d. +0.920 kJ O e. -0.920 kJ
