A bomb calorimeter has a heat capacity of $783 \mathrm{J} \mathrm{x} °{{\mathrm{C}}^{-1}}^{ }$ and contains 254 g of water, which has a specific heat of $4.184\mathrm{J}\times {\mathrm{g}}^{-1}{\times }^{\circ }{\mathrm{C}}^{-1}$ . How much heat is evolved or absorbed by a reaction when the temperature goes from $23.73°\mathrm{C}$ to $26.01°\mathrm{C}$?
