A phase diagram shows the relationship between
pressure, volume, and the three phases of matter
temperature, pressure, and the three phases of matter
temperature, volume, and the three phases of matter
A single homogeneous physical state is referred to as
pressure
temperature
a phase
The phase change that results from a solid going directly into the gaseous phase is
sublimation
melting
vaporizing
On a phase diagram, the intersection of the solid, liquid, and gaseous lines is known as the
intersection point
fluid point
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
boiling point
triple point
Beyond the critical point, the phase of the substance is referred to as a
super solid
supercritical fluid
super gas
Above the critical temperature, it is impossible to
apply enough pressure to condense the gas to a liquid
measure the temperature of a substance
apply enough pressure to freeze a liquid
The lines on a phase diagram represent the temperatures and pressures at which
one phase of the substance is present
two phases of the substance are present
all three 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
dependent variables
independent variables
constants
Questions 10 and 11 refer to the following diagram:
At 1.0 atmosphere of pressure and 150°C, what is the phase of water?
gas
liquid
solid
Questions 10 and 11 refer to the following diagram:
What phases of water are present at a temperature of 0.01°C and 0.006 atm of pressure?
solid and liquid
solid and gas
solid, liquid, and gas
