Day to day and real-life instances are given below. Identify which of the following is/are example/s of the First Law of Thermodynamics by writing YES if it is and NO, if otherwise. _____ 1. An electric light bulb transforms electric energy into light energy. _____ 2. Smoke dispersal when burning wood. _____ 3. Plants undergo photosynthesis which enable fruit-production and blooming of flowers. _____ 4. Water overflowing in a boiling pot. _____ 5. We eat food which makes us able to do our daily tasks such as walking, thinking, and finish our modules
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.
