| Question | Answer |
|---|---|
| Matter | Anything that has mass and takes up space |
| Mass | the amount of matter (or stuff) in an object |
| states of matter | solid, liquid, gas, plasma, Bose-Einstein Condensate |
| solid | A state of matter that has a definite shape and a definite volume |
| liquid | A state of matter that has no definite shape but has a definite volume. |
| gas | A state of matter with no definite shape or volume |
| Bose-Einstein Condensates | a state of mater when a group of atoms cooled very close of absolute zero |
| Plasmas | a state of matter formed at extremely high temperatures when electrons are stripped from neutral atoms. Stars are predominantly composed of these. |
| Dissolves | to pass into a solution with a liquid |
| Evaporates | changes from a liquid to a gas |
| Properties of matter | color, shape, texture, odor, taste, mass weight, volume, density and magnetism |
| Color | observable Characteristics |
| Shape | Form |
| Texture | The feel, appearance, or consistency of a surface, substance, or fabric. |
| Oder | intensity of smell |
| Magnetism | The force of attraction or repulsion of magnetic materials |
| Hardness | A measure of how easily a mineral can be scratched |
| Reflectivity | The characteristic of being capable of or producing reflection |
| Solubility | A measure of how much solute can dissolve in a given solvent at a given temperature. |
| Electrical conductivity | is a measure of how well electricity can move through a material |
| Electrical Conductors | Allow electricity to flow easily |
| Electrical Insulators | A material that slows or stops electricity |
| Thermal conductivity | The ability of an object to transfer heat |
| Thermal energy | The energy of moving particles |
| Thermal Insulators | objects that don't conduct thermal energy |
| Heating | increases the energy of the particles; they move faster and move farther apart |
| Melting point | The temperature at which a substance changes from a solid to a liquid. |
| Boiling Point | the temperature where a liquid becomes a gas |
| Physical changes | Any change that DOES NOT alter the chemical composition of a substance. |
| Conservation of Matter | matter can neither be created nor destroyed in physical and chemical changes |
| Condensation | Is the change from a gas to a liquid |
| Mixture | A combination of materials. It is a physical property in which the individual molecules enjoy being near each other, but their fundamental chemical structure does not change. |
| Chemical Changes | a change in which one or more substances combine or break apart to form new substances |
| Chemical reaction | Process that changes, or transforms, one set of chemicals into another set of chemicals |
| How do you know whether a chemical change has occurred? | A chemical change has occurred if an entirely new substance has been created. For example, breaking a glow stick makes a chemical reaction happen and it lights up. |
| Signs of a chemical reaction | change in temperature, formation of bubbles, precipitate (solid) forms, color change, change in smell, difficult to reverse |
| Does the conservation of matter apply to chemical changes? | Yes, because the total mass of matter is the same as the total mass after the reaction. |
