Compound X and Y are being tested for their capacity as insulators. a. In the first experiment, compound X after being heated to 200 F it was transferred to a 0.100L water bath, the initial temperature of the water bath is 25 C, the final temperature after compound X was dropped was 30 C. What is the specific heat in calories? (specific heat of water is 1 calorie/gram °C = 4.186 joule/gram °C) b. The same experiment was conducted with chemical Y but the final temperature of the water bath was 308 K. What is the specific heat in Joules? c. Which of the two chemicals would be a better insulator? and Why?
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.
