How do I calculate the final temperature of a mixture? Mass of empty cup and lid: 9.94 g Mass of the cup, lid, and cool water: 34.92 the temperature of cool water: 26.9 degrees celsius specific heat of water: 4.184 joules/grams degrees celsius
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.
How do I calculate the final temperature of a mixture?
Mass of empty cup and lid: 9.94 g
Mass of the cup, lid, and cool water: 34.92
the temperature of cool water: 26.9 degrees celsius
specific heat of water: 4.184 joules/grams degrees celsius
the temperature of hot water: 78.5-degree celsius
mass of cup, lid, and water mixture: 74.22g
the observed final temperature of mixture: 57.5 degrees celsius
mass of hot water: 64.28g
mass of cold water: 24.98g
