The following information is given for silicon aty1 atm: AHvap (2355.00°C) = 1.058 × 10ª J/g AHfus (1410.00°C) = 1.653 x 103 J/g = 2355.00°C Tm = 1410.00°C Specific heat solid = 0.7110 J/g °C Specific heat liquid 0.9080 J/g °C kJ of heat are needed to raise the temperature A 45.60 g sample of solid silicon is initially at 1400.00°C. If the sample is heated at constant pressure (P = 1 atm), of the sample to 1688.00°C.
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.
The heat capacity is the ratio of the energy supplied in the form of heat to the rise in the temperature of the system. The mathematical relation for the heat capacity is shown below.
