The freezing point is the temperature at which a liquid will . The boiling point is the temperature at which a liquid will . The melting point is the temperature at which a substance will . Different substances will have different "points" at which they change states due to their particular physical .

Which of the following describes a boiling point?A.Phase change from a liquid to a gas occurring at a specific temperature and pressureB.Phase change from a gas to a liquid occurring at a specific temperature and pressureC.Phase change from a solid to a liquid occurring at a specific temperature and pressureD.Phase change from a solid to a gas occurring at a specific temperature and pressureSUBMITarrow_backPREVIOUS

The boiling point of a compound is the temperature at which a liquid is converted to the phase.
