| all matter is made of --- molecules | moving |
| particles move in (same or different)directions at (same or different) speeds | different; different |
| what is a thermometer used to measure? | temperature |
| an increase in the volume of a substance because of an increase in temperature | thermal expansion |
| STUDY TEMPERATURE SCALES | :) |
| absolute zero is the lowest temperature on the --- --- | kelvin scale |
| absolute zero is the temperature at which molecular enery --- | stops |
| what are the three units used to measure temperature? | Farenheit, celcius, kelvin |
| list 3 things that involve thermal expansion | expansion joints, thermostats, and hot air balloons |
| the energy transferred between objects that are at different temperatures | heat |
| energy is transferred from the object with the --- temperature to the object with the --- temperature | higher; lower |
| the total kinetic energy of the particles that make up a substance | thermal energy |
| does thermal energy relate to the amount of the substance? | yes |
| when the 2 objects that are touching reach the same temperature | thermal equilibrium |
