| definite volume and a definite shape | A solid is a state of matter that has a |
| viscosity | The resistance of a liquid to flowing is its |
| free to move in a container but remain in close contact with one another | Particles of a liquid are |
| gas | In which state of matter do the particles spread apart and fill all the spae available to them |
| a solid turns directly into a gas | During the process of sublimation |
| surface tension | The surface of water can act like a sort of skin due to a property of liquids called |
| melting point | The freezing point of water is the same as its |
| a liquid becoming a gas | What is vaporization |
| vaporization, then condensation | An uncovered pot of soup is simmering on a stove, and there are water droplets on the wall above the back of the stove. What sequence can you infer has occured |
| the pressure of the air above the substance | The boiling point of a substance is affected by |
| sublimation | In cold climates, the amount of snow on the ground may decrease even if the temperature stays below zero degrees Celsius. The process that best explains this event is. |
| a substance that flows | a fluid is |
| volume | the amount of space that a gas takes up is its |
