Question | Answer |
---|---|
A phase diagram shows the relationship between: | temperature, pressure, and the three phases of matter |
A single homogeneous physical state is referred to as | A Phase |
The phase change that results from a solid going directly into the gaseous phase is: | sublimation |
On a phase diagram, the intersection of the solid, liquid, and gaseous lines is known as the ? | triple point |
On a phase diagram, the temperature and pressure at which the phase boundary between the liquid and gas ceases to exist is called the ? | critical point |
Beyond the critical point, the phase of the substance is referred to as a ? | supercritical fluid |
Above the critical temperature, it is impossible to ? | apply enough pressure to condense the gas to a liquid |
The lines on a phase diagram represent the temperatures and pressures of ? | two phases of the substance are present |
On a phase diagram, temperature and pressure can either be varied or held constant. These factors are referred to as ? | independent variables |
When a substance goes from a solid to a liquid phase, this phase change is known as ? | melting |
When a substance goes from a liquid to a solid phase, this phase change is known as ? | freezing |
The phase change that results from a gas going directly into the solid phase is: | deposition |
