Collecting Butane Gas The purpose of the lab was to determine the molecular mass of Butane‚ and this was done by using the ideal gas law (PV=nRT). The materials used were: match‚ funnel‚ bucket‚ cylinder‚ thermometer‚ lighter‚ scale‚ and a wooden flynt. These materials are used to help collect and test the Butane gas. Butane gas was used because it is ideal at standard temperature and pressure. Procedure: 1. Rinse bucket and fill three fourths full. 2. Rinse all glassware. 3. Place

doubted himself. Grant Achatz‚ is the only American chef to master the art of Molecular Gastronomy. People sought after progressive cuisine to at least experience it once. This family man and cancer survivor is a prime example of heroism. With knowledge of molecular gastronomy‚ there’s some weight to his name. Being able to take foods and give them new tastes and textures‚ is what gave his cuisine’s popularity. Molecular gastronomy is seen as “manipulating” the ingredients‚ instead of cooking them

breakthrough came as she observed painters decorating the bank windows for the holidays. Rather than remove their mistakes entirely‚ the painters simply covered any imperfections with an additional layer. The quick-thinking Graham mimicked their technique by using a white‚ water-based tempera paint to cover her typing errors. When the other secretaries realized how well the invention worked‚ they flooded Graham with requests for their own supplies. The now-famous woman inventor sold her first batch of "Mistake

The samples were categorized as liquids and solids. Under the liquid samples were the subcategories of water and liquids other than water. Subcategories for solid samples were regularly-shaped and irregularly-shaped. All in all there were seven samples‚ namely water‚ isopropyl alcohol‚ coconut oil‚ wooden block‚ marble‚ pebbles‚ and an unknown liquid sample. For the density of water‚ a clean and dry 100ml graduated cylinder was weighed and 50ml of water was added into the graduated cylinder. The

The study of shelf life for liquid biofertilizer from vegetable waste showed that contrary to the traditional advice that liquid biofertilizers produced from fermentation by effective microorganisms‚ should be used within three months of production‚ the liquid biofertilizer produced from vegetable waste still contains high amount of viable microbial population after four months of storage with no significant effect of the presence or absence of light (Ngampimol and Kunathigan‚ 2008).

Liquid Crystal Displays (LCD) – Working We always use devices made up of Liquid Crystal Displays (LCDs) like computers‚ digital watches and also DVD and CD players. They have become very common and have taken a giant leap in the screen industry by clearly replacing the use of Cathode Ray Tubes (CRT). CRT draws more power than LCD and are also bigger and heavier. All of us have seen an LCD‚ but no one knows the exact working of it. Let us take a look at the working of an LCD. We get the definition

absolute zero (-459 degrees Fahrenheit‚ 0 degrees Kelvin‚ -273 degrees Celsius) to liquid nitrogen temperatures (-321 F‚ 77 K‚ -196 C)‚ they have no electrical resistance. The temperature at which electrical resistance is zero is called the critical temperature (Tc) and varies with the individual material. For practical purposes‚ critical temperatures are achieved by cooling materials with either liquid helium or liquid nitrogen. The following table shows the critical temperatures of various superconductors:

Liquid Gold “The sounds of gunshots rang out throughout the town‚ piercing the veil of quiet like a hot knife through butter. Bushranger PJ Sebastian winced at the sound of every shot‚ keeping his fingers crossed and begging that none of the shots hit their mark. Desperately‚ he limped towards the tree line‚ as if he had any other choice in the matter‚ begging that the tall‚ menacing oak and gum trees could protect him from his assailant. Blood was pouring out of his thigh. He clutched at the wound
