Transcript of Unit 3 - Heat and Temperature Mind Map

Heat and Temperature
Measuring Temperature
Thermometors
Thermocouple
Bimetallic Strip
Infrared
Galileo Thermometer
Thermoscope
Scales
Kelvin
Good for big temperatures
and very small temperatures
Requires using math to convert energy into temperature
Fahrenheit
Freezing point of water
Body Temperature of his wife
32 F
98 F
Celcius
Freezing Point of Water
Boiling Point of Water
100 C
0 C
Particle Model of Matter
Everything is made up
of tiny particles too small
to be seen
All particles are
constantly in motion
Particles have
empty space
in-between them
The speed of a substances
particles determines it's
temperature
Fast moving particles
have a high temperature
Slow moving particles
have a lower temperature
Expand
Contract
Less dense and rise
More dense and fall
Energy
E
Energy Transfer System
Ability to do work
Law of Conservation of Energy
1) Source of Energy
2) Transfer of Energy (Conduction, convection, radiation)
3) Output - what work was done?
Thermal Energy
Movement of particles
to do work
heat
Energy can not be created or
destroyed; energy can only be
converted into one form or another
Energy Transfer
Always hot
to cold
Radiation
No matter
Energy travels as a wave
Conduction
Convection
particles collide to transfer energy
Insulator
Conductor
Only in liquids and gases
Diagram of convection
Sources of Energy
geothermal
hydro
coal
petroleum
solar
tidal
nuclear
biomass
wind
Model of matter
Phase Changes
Gas
Fastest particles
No Bonds
Liquid
Medium particle speed
Some
Bonds

Solid
Slowest moving particle
All
particles
bonded

Particles
slow down
and bond
Particles
speed up
and break
bonds
Evaporation
Freezing
