Recall the last time you bought a cup of coffee or hot chocolate on a particularly cold day. The cup likely felt warm when you held it in your hand. The cup your beverage came in is not too different from the ones we used in this experiment. Based on this, do you think a coffee cup is a perfect insulator? If not, how might this affect your results? Group of answer choices No; the specific heat calculated is lower than it should be due to the heat lost Yes; the specific heat calculated is lower than it should be due to the heat lost No; results will not be affected since the calorimeter contains all heat indefinitely Yes; results will not be affected since the calorimeter contains all heat indefinitely
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.
