Phase Change

Choose the correct answer for the following description:

Liquid that is below its saturated point.

Liquid that it is not about to vaporize

• Subcooled Liquid

• Saturated Liquid

• Liquid-Vapour Mixture

• Liquid at atmospheric pressure

Choose the correct answer for the following descriptions:

A liquid at equilibrium with its vapour state at the boiling point.

A liquid that exists at the saturation temperature or boiling point that corresponds to the existing pressure.

If any energy is added to the liquid at constant pressure, some of the liquid would boil. During the boiling process the temperature will remain constant.

• Compressed liquid

• Saturated Liquid

• Liquid-Vapour Mixture

• Boiled Liquid

Choose the correct answer for the following descriptions:

Liquid and vapour phase coexist in equilibrium

• Saturated steam

• Saturated Liquid-Vapour Mixture

• Liquid-Vapour Mixture

• Superheated steam

Choose the correct answer for the following descriptions:

A vapor that is about to condense.

A vapour that exists at the saturation temperature (T = T_sat) that corresponds to the existing pressure.

If any energy was removed from the vapour at constant pressure, some of the vapour would condense.  During the process of condensation the temperature would remain constant.

• Superheated steam

• Supercritical steam

• Saturated Liquid-Vapour Mixture

• Saturated steam

Choose the correct answer for the following descriptions:

Steam at any pressure and temperature when the heat content of vapour is higher than that at saturated vapour state.

The removal of a small amount of energy will NOT cause the vapour to condense, its temperature will just decrease.

• Superheated steam

• Supercritical Steam

• Triple Steam

• Saturated steam
