Atom | The basic building block of matter that has three particles: proton, neutron, and electron. |
State | The 3 to 5 physical conditions of matter found on Earth; solid, liquid, gas, plasma, and Bose-Einstein Condensate. |
Solid | A state of matter that when observed has a definite shape, size and mass. |
Mixture | Putting together 2 or more substances that can be easily separated. |
Solution | Putting together 2 or more substances that cannot be easily separated. |
Property | It describes how an object looks, feels, or acts. |
Melting point | The temperature at which a solid becomes a liquid, this happens when a solid is heated. (Energy is added) |
Condensation | When vapor or gas cools and changes to a liquid. |
Boiling point | Temperate at which a liquid becomes a gas or vapor. |
Evaporation | When a liquid changes to a gas. Heat makes water evaporate faster. |
Freezing point | The temperate when a liquid becomes a solid. |
Gas | A state of matter whose atoms have a lot of energy (move quickly) and do not have a definite shape, mass or volume. |
Liquid | A state of matter whose atoms have more energy than a solid and less energy than a gas. It does not have a definite shape. Atoms are close together and move around. |
Matter | It is anything that takes up space and has mass. |
