13. A student takes 22 grams of an unknown metal places them into a boiling water bath She leaves the pellets in the bath for 15 minutes to make sure that they are at a steady temperature. She then pours ther into a beaker containing water and records her data on the data table below Mass of Metal 22g Initial Temperature of Metal 100 Mass of water 90g Initial Temperature of Water 23 C Final Temperature of Water and Metal 28 C a. How much energy did the water gain? b. What is the specific heat of the metal? Enter both final answers
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.
