Heat is the energy that flows from the higher temperature
object to the lower temperature object when the two are placed
When heat Q is added to an object of mass m, its
temperature increases according to the equation Q = mc(Final T
Initial T0, where c is the specific heat capacity of the
When two objects are in contact and are isolated from the
environment, the heat gained by one is equal to the heat lost
by the other; this is simply the conservation of energy.
The amount of heat added (or removed) per kilogram as a
substance changes its phase (ice to water, for example) is the
latent heat. The latent heat of fusion is the amount of heat
that must be added to 1 kg of ice at 0 C to transform it to
water at 0 C. The latent heat of vaporization is the amount of
heat that must be added to 1 kg of water at 100 C to transform
it to steam at 100 C.
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.
