Using specific heat capacity to find temperature change A chemical reaction takes place inside a flask submerged in a water bath. The water bath contains 5.80 kg of water at 22.6 °C. During the reaction 116. kJ of heat flows out of the flask and into the bath. -1. -1 Be sure your Calculate the new temperature of the water bath. You can assume the specific heat capacity of water under these conditions is 4.18 J.g.K answer has the correct number of significant digits.

Thermochemistry
Thermochemistry can be considered as a branch of thermodynamics that deals with the connections between warmth, work, and various types of energy, formed because of different synthetic and actual cycles. Thermochemistry describes the energy changes that occur as a result of reactions or chemical changes in a substance.
Exergonic Reaction
The term exergonic is derived from the Greek word in which ‘ergon’ means work and exergonic means ‘work outside’. Exergonic reactions releases work energy. Exergonic reactions are different from exothermic reactions, the one that releases only heat energy during the course of the reaction. So, exothermic reaction is one type of exergonic reaction. Exergonic reaction releases work energy in different forms like heat, light or sound. For example, a glow stick releases light making that an exergonic reaction and not an exothermic reaction since no heat is released. Even endothermic reactions at very high temperature are exergonic.
