A 53.0 gram nickel bolt (c = 0.44 J/g°C) is heated until it glows and is then dropped into 722 grams of water (originally at 25°C) After they reach equilibrium, they both have a temperature of 42°C. What was the high temperature of the bolt? %3D Note: 1 kilogram = 1000 grams 1 Calorie = 1 kcal = 1000 calories OF to °C: [(T-32 ) x 5 ]-9 9. A 65.5 gram piece of glass (c = 0.840 J/g°C) is heated to 177°C and dropped into a beaker containing 450 grams of ethanol (c = 2.46 J/g°C.) After they reach equilibrium, their temperature is 51.0°C. What was the starting temperature of the ethanol? lili
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.
