Concept explainers

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.

Heat Storage C2. 1-3

You often do your ARCH 140 homework sitting in one of the many Berkeley cafes. One day, you realize the heat flow
dynamics of the café represent a great example of the many topics we discuss in class. Having finished your
homework, you're inspired to do a little extra work and conduct your own thermal analysis of the setting. The next day
you visit the café during two different one-hour periods and record your observations below.
Because the café is very popular, it usually has enough people inside to keep the indoor temperature above 22 °C.
When internal heat gains are insufficient, the heater will turn on, but you can ignore that situation in this problem. But
when internal heat gains are too high, and it gets too warm, the café has a variable-speed fan rated at 1.42 m3/s to
bring in outside air for ventilation and cooling. To simplify the calculations, assume the envelope is perfectly insulated,
and the only heat transfer is from air exchange.
