||||
| molecule | The smallest whole part of a compound. Atoms of elements can also be grouped to form a molecule.
🗑
|
||||
| compound | A substance made when two or more elements are joined together and lose their properties.
🗑
|

| solid | A phase of matter that has a definite shape and definite size. Particles in a solid are tightly packed and vibrate slightly. The particles are arranged in order.
🗑
|
||||
| liquid | A phase of matter that takes up a definite amount of space but has no definite shape. Particles in a liquid are close together and slide past each other. The particles are not arranged in order.
🗑

||||
| temperature | The measure of heat energy present.
🗑
|
||||
| boiling point | The temperature at which a liquid changes to a gas.
🗑
|
||||
| freezing point | The temperature at which a liquid changes to a solid.
🗑
