The initial temperature of a bomb calorimeter is 28,50°C. When a chemist carries out a reaction in this calorimeter, its
temperature decreases to 27.45°C. If the calorimeter has a mass of 1.400 kg and a specific heat of 3.52 J/g °C), how much
heat is absorbed by the reaction?
Use 9-MCAT
140 J
418 J
1.470J
5.170 J
