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.
In this learning activity you'll explore how an Exclusive-OR gate operates by using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.
Financial Statements: What Are They? What Do They Mean?
Learners read about the most common forms of financial statements including balance sheets, cash flow statements, and profit and loss statements. A brief quiz completes the activity.
The Effect of Temperature on the Vapor Pressure of a Liquid
Learners examine how vapor pressure is calculated. The vapor pressure of a liquid increases with increasing temperature. If the heat of vaporization and the vapor pressure at one temperature are known, the vapor pressure at a second temperature can be calculated.
