Select the true statement(s): Water has a higher specific heat capacity than lead and both start at the same temperature.. That means that it the water will need to absorb more heat energy than the lead to increase by the same temperature. Water has a higher specific heat capacity than lead and both start at the same high temperature and are allowed to cool The item with the higher specific heat capacity will release less heat energy than the other as they both decrease to the same temperature. One gram of aluminum and 1 gram of iron (both at the same temperature) were dropped into separate containers of hot water. After they each absorb 100 J of heat from the water, the aluminum is at the higher temperature.
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.
