WebSep 24, 2013 · What phase changes occur in the water cycle? Condensation: change from a gas to a liquid -- water vapor in the air forms tiny drops of liquid water or ice (clouds). This is followed by ... WebIn the video here, Sal uses a horizontal line through the phase diagram. But, it doesn't have to be horizontal. Imagine a vertical line through this diagram-- for water, choose 100 degrees C. As long as you are at 100 C, you can change the phase by changing the pressure on the system. This kind of process is called "adiabatic". 2 comments

WebA phase change is a physical process in which a substance goes from one phase to another. Usually the change occurs when adding or removing heat at a particular temperature, known as the melting point or the boiling point of the substance. The melting point is the temperature at which the substance goes from a solid to a liquid (or from a ... WebSep 20, 2024 · You can bring the substance to an equilibrium between two phases by changing the volume until the pressure in the container equals the equilibrium vapour pressure - a fixed pressure at that temperature. You can then continue to change the volume (all the while keeping the temperature constant). WebNov 27, 2024 · A phase change is when matter changes to from one state (solid, liquid, gas, plasma) to another. (see figure 1). These changes occur when sufficient energy is supplied to the system (or a sufficient amount is lost), and also occur when the pressure on the system is changed.

"WebWhy do Phase Changes Occur? When temperature or pressure change of a system occurs, phase changes occur. When the temperature or pressure increases, the interaction between the molecules increases. Similarly, when the temperature decreases, it is easier for molecules and atoms to settle into a more rigid structure. " - How do phase changes occur
