What is saturated phase?
The saturated phase is a phase in which a substance exists at a temperature and pressure where it is in equilibrium between its liquid and vapor states. In this phase, the substance's properties such as temperature, pressure, and composition remain constant until all the substance has completely vaporized or condensed.
True or False- The freezing point of a substance is equal to the melting point of a substance?
True. The freezing point of a substance is the temperature at which it changes from a liquid phase to a solid phase, while the melting point is the temperature at which it changes from a solid phase to a liquid phase. In equilibrium, the freezing point and melting point of a substance are the same.
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 is a property that determines how a substance can be converted to another substance?
This property is called chemical reactivity.
What temperature at which a substance in the liquid phase transforms to the gaseous phase refers to the substances?
The temperature at which a substance in the liquid phase transforms to the gaseous phase is called the boiling point for pure substances. It is a characteristic property of the substance and remains constant under a specific pressure.
What is the relationship between vapor pressure and phase diagram in a substance?
The vapor pressure of a substance is related to its phase diagram because the vapor pressure determines the conditions at which the substance transitions between different phases (solid, liquid, gas). The phase diagram shows how the substance behaves at different temperatures and pressures, including the points where the substance transitions between phases. The vapor pressure at a specific temperature and pressure can help determine the phase of the substance on the phase diagram.
What determines the mass and volume of a substance?
The density of the substance.
When a substance changes from one physical form to another you say the substance has had a what?
When a substance changes from one physical form to another, you say the substance has had a phase change or undergone a phase transition.
What determines the electron-group of a molecule?
the thing that determines it is the type of molecules that are in the substance
Which phase always fills its container?
when a substance is in liquid phase
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.

What do you mean by phase angle?
it determines the displacement as well as the direction of motion of vibrating particle in the phase.

In this phase, the substance's properties such as temperature, pressure, and composition remain constant until all the substance has completely vaporized or condensed.
What does the density of a substance determine?
It determines the mass of the substance per unit volume.
