An insulated container is used to hold 44.4 g of water at 29.0 C. A sample of copper weighing 9.40 g is placed in a dry test tube and heated for 30 minutes a water bath at 100.0 degrees * C . The heated test tube carefully removed from the water bath with laboratory tongs and inclined so that the copper sildes into the water in the insulated containerGiven that the specificheat salld copper is 0.385 J/(g C) ,calculate the maximum temperature of the water the insulated container after the copper metal is added.
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.
