What will my heat gained by the calorimeter be? and total heat
gained? Also do I represent heat loss of metal as
negative?
Part 2: Determining the Specific Heat Capacity of an Unknown Metal Data Trial 2 Trial 1 4.62g Mass of calorimeter Mass of calorimeter + water Mass of metal 102.35 g 81.63 g 22.1 C Initial temperature of water in calorimeter Initial temperature of metal 98.8 C Final temperature of calorimeter + added metal 27.5 C Calculations Trial 2 Trial 1 97.73 g Mass of water in calorimeter (mcw) Mass of added hot metal (MHM) 81.63 g Temperature change of cool water (Qcw) 5.4 C Temperature change of hot metal (ATHM) -71.3 C Heat gained by the cool water (Qcw) 2.2×1013 J (Show calculations for one trial) Qcw=mx Specific Heat Capacity Water x Chng.
