Today’s Lesson:
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.
