Questions A 30.0 g metal cube is heated to a temperature of 100.0°C and placed in a coffee-cup calorimeter containing 50.0 g water at 24.7°C. The coffee-cup calorimeter is a non-ideal calorimeter. -4metal = 4water + ¶calorimeter Which of the following statements are true? Select all that apply. Heat is lost by the hot metal. The calorimeter constant is greater than zero. Collected Lab Data Temperature of cold water (°C) 3.0 Temperature of hot water (°C) 89.0 Volume of cold water (mL) 97.0 Volume of hot water (mL) 87.5 Final temperature after mixing (°C) 43.0 Mass of cold water (g) 97.0 Mass of hot water (g) 87.5 Calorimeter constant (J/°C) 15
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.
