Ideal gas law: PV = nRT, where P is the pressure, V is the
volume, n is the number of moles, R = 8.314 J/(mole. K) is the
universal gas constant, and T is the temperature in K.
The number of moles n = N/Na, where N is the number of
atoms (or molecules), and Na is Avogadros number.
The root mean square speed of a molecule, Vrms, is equal to
the square root of 3RT/M, where M is the molecular mass of the
The translational kinetic energy of n moles of a gas is
In a gas at a given temperature, there is a distribution of
speeds of the molecules. Some molecules move relatively slowly
and others move relatively fast.

Lecture Slides are screen-captured images of important points in the lecture. Students can download and print out these lecture slide images to do practice problems as well as take notes while watching the lecture.
The book offers a complete review of your AP course, strategies to give you the edge on test day, and plenty of practice with AP-style test questions. It includes full length practice exams modeled on the real test and all the terms and concepts you need to know.
This book includes a review of all the topics tested including vectors, kinematics, fluid mechanics, optics and nuclear physics. Additionally, the book includes two full length tests made complete with descriptive solutions, and quick study tables for Physics B formulas and equations.
