|---|---|
| the temperature at which a liquid will turn to a gas | boiling point |
| a change that forms a new substance (burn paper to make a gas, ash and heat | chemical change |
| the ability of a substance to change into a new substance with different properties (will burn, will rust) | chemical property |
| the change of a state from a liquid to a solid | freezing |
| a material that does not conduct something well, but instead stops the flow of electrical, heat, sound energy (ex. plastic) | insulator |
| a state of matter with a definite volume, but takes the shape of its container. Particles move slowly and are close together. | liquid |
| the amount of matter in something | mass |
| anything that has mass and takes up space | matter |
| the temperature at which a solid turns into a liquid | melting point |
| a change in size, shape, or state of matter, now new substances are formed. (ex. cut paper, freezing a liquid) | physical change |
| a characteristic of matter that can be measured or detected with the senses | physical property |
| a state of matter in which volume and shape are definite, particles are tightly packed and vibrate. | solid |
| the forms that matter can take: solid, liquid, gas or plasma | states of matter |
| a state of matter without a definite shape or volume, particles are spread out and move quickly | gas |
