Two substances A and B, initially at different temperatures, arethermally isolated from their surroundings and allowed to comeinto thermal contact. The mass of substance A is twice the massof substance B, but the specific heat capacity of substance B isfour times the specific heat capacity of substance A. Whichsubstance will undergo a larger change in 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.
Two substances A and B, initially at different temperatures, are
thermally isolated from their surroundings and allowed to come
into thermal contact. The mass of substance A is twice the mass
of substance B, but the specific heat capacity of substance B is
four times the specific heat capacity of substance A. Which
substance will undergo a larger change in temperature?
