Description
Analyze the most central idea of thermodynamics: temperature. Investigate the origin of different temperature scales and the various methods for measuring temperature. See how the concept of temperature is a consequence of the zeroth law of thermodynamics, which deals with the nature of thermal equilibrium.

Continue your study of chemical reactions by contrasting two different types of reactions, shedding light on a crucial factor called the reaction quotient. In the first reaction, study pure compounds reacting together. Then look at dissolved compounds reacting. Learn how to compute the reaction quotient at any concentration.

Description
Discover that the values for work and heat in a given system depend on the path taken to get to a particular state. But note that the sum of work and heat does not depend on the path; it is a constant. This remarkable fact is the foundation of the first law of thermodynamics.
