6. Heat - movement of thermal energy (TE) from a warmer object to a cooler
“heating” an object means adding TE to it.
“Cooling” means removing TE from it.
When the temperature of 2 objects is equal - no heat can flow between them.
Temperature - the average KE of the particles that make up a material
atoms or molecules
2. adding (or losing) thermal energy increases (or reduces) KE of particles
as average KE increases - so does temperature.
as average KE lowers - so does temperature
3. Two material may be the same temperature but contain different amounts of thermal energy.
ex. A pond and a puddle at the same temp
pond would have more thermal energy because its larger
in general solids and liquids have more TE than gases at same temp
particles are closer together so have more PE
4. Temperature is measured in degrees using a thermometer.
Degree Fahrenheit and Celsius are most common
Degrees Kelvin only used in science
5. Conversions
6. Heat - movement of thermal energy (TE) from a warmer object to a cooler
“heating” an object means adding TE to it.
“Cooling” means removing TE from it.
Energy - causes change to matter
KE - energy due to motion
PE - Stored energy due to position of two objects that interact
Substances have Energy contained in their particles (atoms)
The Kinetic Theory of Matter states that all particles in all states of matter are in constant motion.
Atoms move differently in different states of matter.
Now add to your notes with some independent research:
Use the following website PHET States of Matter Basics
Research and draw diagrams of particles in the three states of matter.
Draw all three states separately.
Do this in your notebook.
add notes or labels to describe the
Particle arrangement.
Particle motion.
Use the following phrases to label your drawings. (Some phrases are used more than once.)
particles vibrate in place
particles move around freely
particles keep a regular shape and arrangement
particles slide over and around one another
particles spread out near the bottom of their container
particle vibrate while they move about
particles fill the entire container
