C)melting
D)sublimation

Question

Quizplus · Accepted Answer

If a solid is heated at a pressure above the triple point pressure, it will undergo a transition to the liquid phase through melting. This transition occurs when the temperature of the solid is raised to its melting point, at which point the solid will begin to liquefy as its molecules gain enough energy to overcome the forces holding them together in the solid state. Condensation and deposition are transitions between the gas and liquid/solid phases, respectively, and sublimation is a transition from solid to gas without passing through the liquid phase.
