Mercury will not wet the glass‚ unlike water and many other liquids ‚[1] and if the glass is tipped‚ it will ’roll’ around inside. APPLICATIONS Dew drops adhering to a spider web. Cohesion causes water to form drops‚ surface tension Causes them to be nearly spherical‚ and adhesion keeps the drops in place

QTC™ Material can be made to withstand extreme temperatures limits. * Used for switches and keyboards. Thermochromic Ink * These materials change colour when there is a change in temperature. * Thermochromic ink comes in two forms: Liquid crystals and Leuco dyes. * Leuco dyes are easier to work with and allow for a greater range of applications. * Applications of thermochromic ink include: flat thermometers‚ battery testers‚ clothing.

place it in the proper holder under the hood. Discussion: Melting point is an example of a physical property. This is lieu of the fact that we are observing a sample without changing the composition of the matter. As there are 3 states (solid‚ liquid and gas)‚ the same matter remains intact in all three states. We use melting point measuring in organic chemistry as this is a method to identify a pure solid compound and compare it to the melting points listed in various sources of published data

Background The melting point of a compound is the temperature at which the solid is in equilibrium with its liquid. A solid compounds changes to a liquid when the molecules acquire enough energy to overcome the forces holding them together. A mixture melting point is useful in confirming and used to indentify an unknown compound‚ which we will be doing in this particular experiment. Purpose Measure the melting points of pure benzoic acid and pure mandelic acid. Determine the eutectic composition

Lab #1: Melting Points of Organic Compounds Report Form May 15‚ 2014 1. A “Melting Point Range” refers to the range of temperature at which a solid melts into its liquid state. 2. Pure compounds have narrow or ‘sharp’ melting point ranges‚ 1°C or less if the compound is very pure. A less pure compound exhibits a broader melting point range‚ between 3°C to 10°C as well as a depressed or lower range. 3. Crushing the sample allows for greater surface area-to-volume ratio of the powder‚ this

You can separate solutions into two categories‚ colligative properties and non-Colligative properties. Colligative properties are different from non-colligative properties because they focus on the dissolved particles‚ not the solute itself. Non-colligative properties depend on the specification of the dissolved particles and the solvent. Colligative properties are properties that depend on the dissolved solutes in the solution. There are four main colligative properties; vapor pressure‚ freezing
