Boyle's Law states that gas volume varies inversely with the pressure at constant temperature and is described by the equation PV = constant. An example of a sample of gas at two conditions of P and V is used to illustrate the law.

Learners view movie clips to determine the solubility of two ionic compounds. They also examine a solubility chart and predict the solubility of compounds.

Students read different definitions of "acids" and "bases." In an interactive exercise, they identify if a substance is an acid or a base.

In this interactive object, learners use the ideal gas law to solve a practice problem.

In this learning activity you'll describe the operation of an AND gate by using a truth table, a waveform diagram, a Boolean Algebra equation, a switch analogy, and a written definition.

In this learning activity you'll review how an OR gate operates using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

This interactive activity represents the grid modeling technique, a heuristic model for choosing a centralized location for a manufacturing or distribution center within a supply chain network. The formula calculates a central point between the suppliers and the markets. This object requires the latest version of Flash Player.

After a brief review, the student solves five practical shop problems using right angle trigonometry.

Learners read an explanation of the debits and credits of accounting as they relate to T accounts and the accounting equation. Illustrated examples are provided.
