Oliver heated a tungsten cylinder weighing 56.382 g in a hot water bath. While that was heating, he added 41.02 g of distilled water to a styrofoam cup calorimeter and measured it's temperature at 21.7 °C. Oliver then added the hot tungsten to the calorimeter and observed a final temperature of 24.4 °C. What was the initial temperature, in °C, of the tungsten cylinder? J Specific Heat of water is 4.184 g.°C Specific Heat of tungsten is 0.132 g.°C Note: Do not use scientific notation or units in your response. Sig figs will not be graded in this question, enter your response to four decimal places. Carmen may add or remove digits from your response, your submission will still be graded correctly if this happens.
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.
