Introduction: Objective To learn how to obtain an accurate melting point using a MELTING POINT APPARATUS‚ then use them to draw eutectic curve and determine the eutectic point. Melting point of a solid is the temperature at which the solid and its liquid form are in equilibrium‚ i.e.‚ molecules move back and forth between the two states at the same rate‚ so both phases remain present. If the temperature of a solid is measured carefully as the solid is heated‚ the temperature will be observed to rise

Hypothesis: The hypothesis of this lab was by using the density of alcohol we could calculate the density of a quartz samples. Controls and Variables: Independent variable: Volume of water and alcohol Dependent variable: The weight of the liquid or solid Controls: The volume of the water should be the same each trial Materials: Triple Beam Balance‚ Graduated cylinder‚ Beaker‚ Quartz‚ Distilled water‚ rubbing alcohol Procedure: 1. Find the mass of the empty graduated cylinder. 2. Fill

given to English engineer Craven Walker who‚ in the late 1940s‚ saw a prototype of the lamp in a pub in Hampshire‚ England. This early version‚ according to the Walker legend‚ was made of "a cocktail shaker‚ old tins and things." He purchased the liquid-filled fixture and set out to make his own. Walker formed the Crestworth Company in Dorset‚ England‚ and over the next 15 years tried to build a better lava lamp. When first marketed under the name Astro Lite in British stores in the early 1960s‚

water-in-oil emulsion‚ the emulsifier coats the water droplets to stop them from separating from the oil. This property makes emulsifiers indispensable in the modern food industry where foams‚ suspensions (particles of solid dispersed evenly through a liquid) and emulsions are often used. Milk is a natural emulsion. It is a mixture of fat droplets in water. Proteins in the milk help to coat the fat droplets and allow them to stay

Nebulizer A nebulizer is a device that is used for breathing treatments such as asthma‚ cystic fibrosis‚ and other respiratory illnesses. It changes liquid medicine into an aerosol. Aerosol is a "mixture of gas and liquid particles‚" and the best example of a naturally occurring aerosol is mist‚ formed when small vaporized water particles mixed with hot ambient air are cooled down and condense into a fine cloud of visible airborne water droplets.

husk pulp to a square plastic container‚ add some water if you think it’s too thick and mix evenly. I usually also add some PVC glue to make the paper stronger. Using a pair of mold and deckle‚ catch the pulp by immersing them down into the pulp liquid then lift them up slowly. Let water flow back from the mold to the pulp for some seconds. lay a sponge on a flat surface and cover it with a wet cotton fabric. Put the mold with pulp layer onto the wet fabric with up side down position (the pulp

of oil to lower its price. The researchers used Jackfruit seeds as alternative source of oil. It is because jackfruit was available in the market. It also has the properties and substances oil has. The researchers gathered the seeds and extracted liquid from it‚ and it was heated. After 5 minutes‚ the researchers removed it from heat. The materials used are Jackfruit seeds‚ grater‚ fine cloth‚ basin‚ stove‚ pan and mortar and pestle. The product produce was more viscous than commercial oil and less
