Matter & Heat
The States of Matter and Heating and Cooling
Term | Definition |
---|---|
thermal energy | the energy that makes particles move |
heat | the flow of energy between objects |
thermometer | a tool used to measure temperature |
gas | matter that has no definite shape or volume |
liquid | matter that has a definite volume, but not a definite shape |
insulator | a material that heat does not move through easily |
solid | matter that has a definite , or certain, amount os space |
conductor | a material that heat easily moves through |
temperature | the measure of how hot or cold something is |
What states of matter can change shape? | gases and liquids |
The more thermal energy an object has, the ___________ the temperature. | higher |
High temperature = | fast particle movement |
Low temperature = | slow particle movement |
When does an object expand? | when the temperature increases |
When does an object contract? | when the temperature decreases |
Which state of matter has the particles most closely packed together? | solid |
Which state of matter has the particles with the most space between them? | gas |
Examples of conductors | items with metal; ex: cooking pans, metal wires |
heat | always goes from a warmer object to a cooler object |
particles | what matter is made up of |
