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

PREPARATION OF ASPIRIN AND DETERMINATION OF THE MELTING POINT Ferrer‚ Lara Melissa V. Faculty of Engineering University of Santo Tomas Manila‚ Philippines ABSTRACT This experiment involved three steps: synthesis of aspirin‚ isolation and purification‚ and the estimation of purity of the final product. The synthesis involved the reaction of salicylic acid and acetic anhydride in the presence of a catalyst‚ phosphoric acid‚ H3PO4. When the aspirin was prepared‚ it was isolated and filtered. The percentage

Our iceberg is melting by John Kotter “Once upon a time a colony of penguins was living in the frozen Antarctic on an iceberg near what we call today Cape Washington.” The following summary will explain the key moments of the fable and how they relate to our lives. First‚ let’s introduce some of the more important penguins – the Leadership Council members. Louis‚ the head of the Leadership Council‚ could perhaps be considered the CEO of the penguin colony. Alice is a smart‚ aggressive member

Salad Bowl vs. Melting Pot There have been many to question and many so called answers to the merging of America and its different citizens. One cannot choose which term is better than the other; they both serve the same cause just in a different example. Along with this perspective‚ however‚ there is another expression that describes the diversity of people in America. It tends to be interpreted in the same way as the “melting pot‚” but actually has a slightly different meaning with a different

America: The Melting Pot The term the melting pot was coined in 1782 by J. Hector St. John de Crevecoeur. It was a term used to describe the new country and all of its new inhabitants. Where people from different countries and different races and ethnicities could come together to form a new race of people; the American. It encompassed taking the good‚ strong qualities from each culture and keeping them to form an overall new culture. “Across four centuries‚ the steady arrival of millions
