Phase (matter) - Wikipedia Increasing the pressure drives the water into the higher density phase, which causes melting. Another interesting though not unusual feature of the phase diagram is the point where the solid–liquid phase line meets the liquid–gas phase line. The intersection is referred to as the triple point. At the triple point, all three phases can coexist.

"Melt-o-matic" Digital Melting Point Apparatus In practice, the melting point test is carried out on a small amount of finely powdered substance contained in a length of 1.5 mm diameter capillary tubing which has been sealed at one end by melting in a gas flame. The depth of the sample in the tube should be 2 - 3 mm after packing the sample in the sealed end by tapping the tube on the bench. melting point determination - SSERC Melting point apparatus.

While the outward designs of apparatuses can vary greatly, most apparatuses use a sample loaded into a ... Mel-Temp Melting Point Apparatus - orgchemboulder.com Set the power level to 5. When the temperature is about 15 degrees below the anticipated melting point, change the setting to that indicated on the graph below. Observe the crystals with your eye about 6" from the lens to prevent accidentally touching the hot apparatus.

PDF Mel-Temp Apparatus - Winthrop University II. Establishing a Precise Melting Point Once an approximate melting point has been established (or if the melting point of the substance is known from the literature) the Mel-Temp apparatus can be used to find the precise melting range for the substance. To establish a precise melting point, a rate of temperature rise of 1 - 2 oC/min must be ... Distillation - Wikipedia Distillation, or classical distillation, is the process of separating the components or substances from a liquid mixture by using selective boiling and condensation. Dry distillation is the heating of solid materials to produce gaseous products (which may condense into liquids or solids).
