Chapter 17 Change of Phase
We have defined temperature and heat.
Ways for heat to transfer: conduction, convection and
Thermal properties of expansion (hot) and contraction. (cold)
Now we can study what happens thermodynamically to matter
Review of Chapter 19
In Chapter 19, we learned that vibrations are periodic
wiggles, and they can propagate or move that energy
through space as a wave.
Waves transmit energy, not matter.
We can use amplitude, frequency, period, and wavelength to
Chapter 23 Electric Current
In Chapter 22, we learned that
Like charges repel, and unlike charges attract.
Every charge creates an Electric field. The direction of the field
lines is the direction that a positive test charge would move.
Charge is conse
Exam 4 Chapters 22, 23, and 24
Chapter 24 - Magnetism
In Chapter 22, we saw that a stationary electric charge creates
an Electric field. It didnt matter if the charge was stationary
All charges create Electric fields, moving or stationary
Chapter 16 Heat Transfer
In Chapter 15, we defined heat as the flow of energy
from Hot to Cold.
In Chapter 16, we talk about How heat moves from Hot
There are 3 ways for heat to move from Hot to Cold.
Conduction -> needs a medium
Chapter 18 - Thermodynamics
The main principles of Thermodynamics are:
1) Energy is conserved. It can change forms, but it can not be
created or destroyed.
2) Heat flows from Hot to Cold.
Absolute zero on Kelvin scale =
no further lowering of temperature
Review Chapter 20
1. Sound is a longitudinal wave, in which the compression and rarefaction pulses travel in the
direction of the wave.
2. Sound needs a medium to travel through. How the molecules and atoms in the medium collide
(density and elasticity) d
Review for Chapter 19
1. What is the definition of frequency?
2. What is meant by the period?
3. What is meant by the wavelength?
4. How is the speed of a wave related to the frequency and the wavelength?
5. If you double the frequency of a wave, does its
Thermodynamics Chapter 15, 16, 17, and 18.
Physics is the study of how things move.
Thermodynamics is the study of how heat moves.
All matter is in made up of molecules and atoms.
Those molecules and atoms are in constant motion.
Anything moving has kinet
