What is the Process of converting a substance from its liquid phase to its gaseous phase?
evaporation!
What is a property that determines how a substance can be converted to another substance?
This property is called chemical reactivity.
What has to be added to a substance to cause a phase change?
Heat energy must be added to or subtracted from a substance to cause a phase change.
Is sublimation a phase change?
Sublimationis the process of transition of a substance from the solid phase to the gas phase without passing through an intermediate liquid phase. Sublimation is an endothermic phase transitionthat occurs at temperatures and pressures below a substance's triple point
What determines the exact age of a substance?
The exact time it was created.
What determines the mass and volume of a substance?
The density of the substance.
What do the lines on a phase diagram represent?
The lines show where a phase changes happens to a substance -
What determines the phase in which water exists by?
At this linksee the phase diagram of water.
What does a phase diagram show for a substance?
A phase diagram shows if a substance is going to be a solid gas, or liquid at a combination of pressure and temperature. It states what phase of matter a substance is at a specific temperature.
What determines the electron-group of a molecule?
the thing that determines it is the type of molecules that are in the substance
How is the thermal energy of a substance related to its state?
The thermal energy of a substance determines its state, since thermal energy, aka internal energy, is the energy the molecules in the substance have. If the energy exceeds the force holding the substance together the substance undergoes a phase change.The physical state of a substance is related to its temperature, the measure of thermal energy. The substance can change states depending on the temperature, e.g. boiling.

Which phase always fills its container?
when a substance is in liquid phase
What do you mean by phase angle?
it determines the displacement as well as the direction of motion of vibrating particle in the phase.
What does the density of a substance determine?
It determines the mass of the substance per unit volume.
What does a density of a substance determine?
It determines the mass of the substance per unit volume.
The phase of matter depends on what?
Heat and pressure are the two main factors that determine a substance's current phase.With high heat a substance's phase drifts toward the gaseous phase while freezing temperatures cause it to move toward its solid phase. With pressure it is the opposite. Higher pressures push the substance toward its solid phase, while lower pressures will encourage the substance to evaporate into its gaseous phase.
