Dry Ice: Sublimation

247 Words1 Page

Dry ice is another name used for solid carbon dioxide that is created by carbon dioxide gas. The gas is then cooled to form a liquid and is it put into a block press or pelletizer. Dry ice is an expamle of a sublimation because it does not become a liquid. Solid carbon dioxide or also known as dry ice, does not melt because it cannot exist as a liquid that is why is changes into a gas. It sublimates much quicker than normal ice melts and last longer. The solid carbon dioxide contains such a cold tempature that it is good to use for a refrigerator. If you want to mail something across the world, just pack dry ice inside of it. So if you want to go on a picnic on a hot summer day, pack your food with dry ice. It is way better than regular

  • Cold Pack And Exothermic Reaction Lab Report

    Chemical bonding, also known as chemical reactions, are happening all around us. From cold packs we use on various injuries to the water we drink, they’re all results of chemical bonding. To be more specific, endothermic and exothermic reactions are both types of chemical reactions that are classified by the heat energy that is either released or absorbed when a reaction occurs. An example of an endothermic reaction would be an “instant cold pack”, which become chilled when activated. As for exothermic reactions, “hot packs” make great examples due to their significant temperature increase in just a few minutes.

  • New State Ice Liebmann Case Study

    255 Words  | 2 Pages

    In my personal and (hopefully) educated opinion, I believe that the national government should look to states when considering national policy. As examined in the 1932 case New State Ice Co. v. Liebmann, the United States Supreme Court found that a state may act as a testing ground for new policies as long as the citizens of that state choose to do so. The benefit of this is that new social and economic legislation can be put into place and be studied without the rest of the nation being put at risk. The Tenth Amendment of the United States Constitution provides this opportunity by stating “all powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the

    Before this invention, drivers had to manually load and unload ice to maintain the temperature inside their trucks. However, Jones's new system eliminated the need for manual loading ("Frederick McKinley Jones" Biography.com). According to the National Inventors Hall of Fame, his automatic refrigeration system maintained a consistent temperature inside the truck, ensuring the preservation of perishable goods ("Frederick McKinley Jones" National Inventors Hall of Fame). This invention not only improved the efficiency of the transportation but also reduced costs and increased the safety of the drivers. Jones's work in this field established him as a pioneer in refrigeration technology, leaving a big impact on the transportation

    The most compelling theory is that Ötzi was assassinated for his high position of power with in his clan. After thorough investigation of the site where Ötzi was discovered (Ötztal Alps) and analysis of the corps historians can infer that the most compelling theory for the death of the iceman is that he was assassinated as part of a power play with in his own clan. This theory is supported by many pieces of evidence. One of these is, the finding of a copper axe near the iceman’s death site and suggesting that the iceman was quite powerful with in his clan. Another supporting piece of evidence is the fact that the arrow was taken out of the iceman’s back, this supports the theory that his attacker did not want to be identified and the fact that

  • Freezing Point Depression Essay

    1183 Words  | 5 Pages

    The phenomenon of freezing point depression has many practical uses. The radiator fluid in an automobile is a mixture of water and ethylene glycol (antifreeze). As a result of freezing point depression, radiators do not freeze in winter (unless it is extremely cold, e.g. −30 to −40 °C (−22 to −40 °F)). Road salting takes advantage of this effect to lower the freezing point of the ice it is placed on. Lowering the freezing point allows the street ice to melt at lower temperatures, preventing the accumulation of dangerous, slippery ice.

    Response Sometimes, no matter how much we try to avoid the danger, we inevitably end up having to face it and to respond to it. Perhaps you saw your potential attacker or attackers and attempted to avoid them moving into a more secure location, yet they followed you there and cornered you. Perhaps you did not see them due to being distracted, and you suddenly find yourself face to face with them. This is a very frightening experience for most of us, and when we are afraid, our bodies react by dumping loads of adrenaline into our bloodstream.
