Sublimation takes place when the temperature and pressure are less than the triple point (the temperature and pressure at which a solid, liquid and gas coexist) of a given substance.

## Where does sublimation occur on a phase diagram?

Sublimation is an endothermic process that occurs at temperatures and pressures below a substance’s triple point in its phase diagram, which corresponds to the lowest pressure at which the substance can exist as a liquid.

## What conditions must exist for a liquid to boil?

During evaporation, only those molecules with a certain minimum kinetic energy can escape from the surface of the liquid. What condition must exist for a liquid to boil? Liquid must be heated to a temp at which particles throughout the liquid have enough kinetic energy to vaporize.

## What do the solid curved lines in a phase diagram represent?

The curved lines represent conditions of pressure and temperature at which two phases exist in equilibrium. What do the curved lines on a phase diagram represent? Gas, volume, and temperature.

## What can a triangular graph be used for?

Triangular graphs are used to show the relationship between 3 sets of data, and are used when the 3 sets of data combined add up to 100%. It is also easy to see the relative proportion/ significance of each component. E.g. if one axis reads 90% and another 10% the latter component is less significant.

## Is triangular plot good?

Square plots denote prosperity, peace and happiness; rectangular plots ensure health and prosperity. A triangular plot or a plot with three corners is associated with negative energies, which bring in a lot of problems. This is good for all spheres of prosperity and happiness.

## How do you plot a Gibbs diagram?

Gibbs diagram is obtained by plotting TDS against Na+/(Na++ Ca2+) and Cl-/(Cl- + HCO3- ). Groundwater suitability for irrigation mainly depends on the concentration of total salinity and sodium related to other ions. Wilcox plot of Na % against EC to assess the irrigation water suitability.

## What is Wilcox diagram?

The Wilcox plot is also known as the U.S. Department of Agriculture diagram. The Wilcox plot is a simple scatter plot of Sodium Hazard (SAR) on the Y-axis vs. Salinity Hazard (Cond) on the X-axis. The Conductivity (COND) is plotted by default in a log scale.

## How do you plot a Wilcox diagram?

## How do you make a Piper diagram?

To use the Piper diagram, firstly, the concentration of anions and cations must be placed in the triangles. Then, a perpendicular line must be drawn from the sample point in one triangle to the diamond and repeat it from the other triangle.

## What is a trilinear chart?

A piper (trilinear) diagram is a specialized graph type for charting the chemistry of a water samples. Origin’s piper diagram is created from worksheet data with column plot designations XYZXYZ. Each column contains the percentage value of each ion group.

## How do you draw a stiff diagram?

By standard convention, Stiff diagrams are created by plotting the equivalent concentration of the cations to the left of the center axis and anions to the right. The points are connected to form the figure.

## How do I create a Gibbs chart in Excel?

Go through the attach excel file. Use the options ‘Bring to Front’ or ‘Send to Back’ by right clicking on mouse to impose the scatter plot on the diagram. Easy way to draw gibbs plot.
