Question | Answer |
What are characteristics of a solid? | definite shape and definite volume |
Describe a solid's molecules. | packed closely together and vibrates in place |
What are two types of solids? Describe them. | Crystalline solid, which has particles are arranged in a regular pattern throughout, and melts at a specific temperature (ex. salt, sugar, snow). Amorphous solid, which are not arranged in a particular pattern and does not melt at a distinct temperature |
What are characteristics of a liquid? | definite volume, but no definite shape |
Describe a liquid's molecules. | free to move, which gives it no shape, but they are packed close together |
What is surface tension? | the result of an inward pull among the molecules of a liquid that brings the molecules closer together. |
What is viscosity? | a liquid's resistance to flow |
What are the characteristics of gases? | no definite shape or volume |
Describe the molecules of gases? | spread apart and constantly moving |
What is matter? | anything that has mass and takes up space |
What is a pure substance? | a pure substance is any type of single material |
What is an element? Describe them. | a pure substance that cannot be broken down. it is on the periodic table |
What is a compound? Describe. | pure substance made up of two or more elements chemically bonded. they can only be separated chemically, they have a chemical formula, and they have a set ratio |
What is a mixture? Describe. | made up of two or more substances (elements, compounds, or both) but are not chemically combined. they have to be separated physically, they are not found on the periodic table, and they have no chemical formula, and they have no fixed ratio |
heterogeneous mixture | can see the different parts, not uniform throughout |
homogeneous mixture | mixed evenly, uniform throughout; a solution is homogeneous, but it does not have to be a liquid |
colloid | mixture containing small, undissolved particles that do not settle out |
suspension | mixture in which particles can be seen and easily separated by settling or filtration. not uniform throughout |
