CHEM.13.4
Sublimation - answer The change that occurs when a solid goes directly to the gas or
vapor state without first becoming a liquid is
vapor pressure - answer This change can occur because solids, like liquids, have a
carbon dioxide - answer Substances that sublime include iodine and solid
phase - answerA graph that shows the relationship between the states of a substance is
called a diagram.
Equilibrium - answer On this diagram, a line between two phases shows the conditions
at which the phases are in
triple point - answeris the only set of conditions at which solid, liquid, and gas phases
coexist.
0.01 degrees Celsius - answerThe triple point for water is a temperature of
0.0060atm - answerand a pressure of
T/F A phase diagram gives information on changes in mass of solids, liquids, and
gases. - answerNEVR TRUE
T/F Water could be made to boil at 105°C by increasing the pressure. - answerALWAYS
TRUE
T/F The sublimation point of a substance refers to the temperature and pressure at
which the substance exists in all three phases of matter. - answerNEVER TRUE
T/F Below the triple point for water, decreasing the pressure will not change water vapor
to ice. - answerALWAYS TRUE
T/F Water has more than one triple point. - answerNEVER TRUE
T/F At 101.3 kPa, the normal boiling point and melting point of water are the same. -
answerNEVER TRUE
melting - answerthe change of a solid to the liquid state
freeze drying - answera method of removing water from food, using sublimation
