Question | Answer |
States of matter depend on the internal [...] of atoms and molecules. | States of matter depend on the internal energy of atoms and molecules. |
liquid -> gas = [...] | liquid -> gas = evaporation |
gas -> liquid = [...] | gas -> liquid = condensation |
liquid -> solid = [...] (aka fusion) | liquid -> solid = freezing (aka fusion) |
solid -> liquid = [...] | solid -> liquid = melting |
solid -> gas = [...] | solid -> gas = sublimation |
gas -> solid = [...] | gas -> solid = deposition |
Phase changes are accompanied by [...] changes. | Phase changes are accompanied by energy changes. |
When matter changes phase (or state), there is an internal energy change, but NOT a [...] change. | When matter changes phase (or state), there is an internal energy change, but NOT a temperature change. |
Intermolecular forces are the forces that pull molecules [...]. | Intermolecular forces are the forces that pull molecules together. |
Kinetic energy pulls molecules [...] each other. | Kinetic energy pulls molecules away from each other. |
Phase diagrams depict the effects of temperature and pressure on [...]. | Phase diagrams depict the effects of temperature and pressure on phase changes. |
The three curves of a phase diagram intersect at the '[...] point'. | The three curves of a phase diagram intersect at the 'triple point'. |
The triple point is the temperature and pressure at which all three [...] of matter exist. | The triple point is the temperature and pressure at which all three phases of matter exist. |
The lines on a phase diagram represent where one [...] ends and another begins. | The lines on a phase diagram represent where one phase ends and another begins. |
The curves of a phase diagram end at the [...] point. | The curves of a phase diagram end at the critical point. |
Above the temperature and pressure of the [...] point, you really can't tell the difference between a liquid and a gas. | Above the temperature and pressure of the critical point, you really can't tell the difference between a liquid and a gas. |
Phase diagrams allow you to predict what [...] a substance will be in at a given temperature and pressure. | Phase diagrams allow you to predict what state/phase a substance will be in at a given temperature and pressure. |
liquid -> solid = freezing (aka [...]) | liquid -> solid = freezing (aka fusion) |
Phase diagrams allow you to predict what state/phase a substance will be in at a given [...] and pressure. | Phase diagrams allow you to predict what state/phase a substance will be in at a given temperature and pressure. |
Phase diagrams allow you to predict what state/phase a substance will be in at a given temperature and [...]. | Phase diagrams allow you to predict what state/phase a substance will be in at a given temperature and pressure. |
