Potoooooooo or Pot-8-Os (foaled in 1773) was a famous 18th-century Thoroughbred racehorse‚ known for his defeat of some of the greatest racehorses of the time and his later life as an influential sire. Pot-8-Os was a chestnut colt bred by Willoughby Bertie‚ 4th Earl of Abingdon‚ in 1773. He was sired by Eclipse‚ his dam Sportsmistress traced to Thwaites’ Dun Mare from the number 38 family and she was sired by Warren’s Sportsman. He was the first foal of Sportsmistress‚ who also produced the Epsom

The goal of this experiment is to find the molar mass of an unknown substance by measuring the freezing point depression of a known amount in an aqueous solution. Freezing point depression is a colligative property of solutions. There are three other properties‚ which are boiling point elevation‚ vapor pressure depression‚ and osmotic pressure. Colligative properties of a solution depend on the amount of solute and solvent molecules and not the specific properties of the molecules. The temperature

4.11 The Design of the Cold Slug Wells The cold material well is located on the movable template opposite to the main flow path or at the end of the runner to trap the cooler advancing front of the melt while allowing hot material to flow into the cavities. The cold well should be slightly larger diameter than the main channel. To pull the sprue out of the sprue bush it has a snatch or pull pin or sucker pin underneath. Ejector pin system can be designed in three different methods: however the undercut

Building a Fire to Fight Nature Jack London’s title for the story "To Build a Fire" starts the reader off with a very basic idea; building a fire. Almost anyone can build a fire. All it takes is a match and some kindling. London’s story is about more then building a fire‚ though. This story is about a man’s belief in himself‚ self-confidence and even arrogance‚ to such an extent that he doesn’t recognize the power of nature around him. London’s story is more like a "Man against Nature" story. London’s

Hypothesis: If...‚ then... Materials: 1. 2 Plastic cups 2. Tap Water 3. Teaspoon 4. Bag of salt 5. Freezer 6. Clock 7. Paper 8. Pencil Procedures: 1. Take plastic cup and pour in one cup water in each 2. Take one teaspoon of salt and mix it in one of cups 3. Put both cups in the freezer 4. Observe. Conclusion: When salt is added to water it slows the freezing process down‚ therefore the freezing point of tap water is higher than the freezing point of salt water

This book examines the broader historical evidence and meaning of food and cooking in African history. Which he hopes to draw students into African and Ethiopian restaurant appearing everywhere‚ as modern diaspora brings immigration to cities all around the world. Stirring the Pot offers a chronology of African cuisine beginning in the sixteenth century

Have you ever seen dry ice‚ well let me show you. To measure the evaporation rate it is important to know that a half pound of dry ice will be placed outside and timed. The same thing will happen but in a cool room. If the dry ice is -109.3°F then it will evaporate in any condition warmer. The hypotheses is that the dry ice in the outside will evaporation faster. It is important to understand this because if you are trying to store dry ice and you put it in a freezer it will still evaporate. So in

As discussed above‚ during DSC analysis two types of FFW and NFW were observed in PS‚ PT‚ and MA samples. The low-temperature XRD technique was used in this study to define the boundary between the FFW and NFW in PS‚ PT‚ and MA samples more accurately. Dowell and co-workers [29] and Shallcross and Carpenter [30] have reported the low-temperature XRD studies on ice structures. The low-temperature XRD analysis has been used by the authors to study the properties of water in low-rank coals [16‚ 26]

Research A phase change is when a substance changes from one state of matter to another. In my experiment I will be freezing water that will turn into ice and see what chemical reaction does different types of salt have on the ice. Salt melts ice mainly because adding salt lowers the freezing point of the water. Pure water freezes at 32°F (0°C). Water with salt (or any other substance in it) will freeze at some lower temperature. The normal freezing point of water is 0 degrees Celsius‚ so if the
