Road to Success Essay

Road to Success Essay Road to Success Essay My long term goals are set in stone, but the road after high school was a challenge in my early high school years, many friends telling me where they are going, and asking me the question â€Å"what are you going to do after high school†. It finally hit me in the beginning of my senior year when I realized I have to do something other then sit around at school. I know I will be attending college, the harder question is where. I have met with my counselor and my parents about what I am going to do after high school, followed up on my financial aid, checked out various colleges. I have come to realize that what I have been doing in high school may not be what I plan on doing the rest of my life. I have been doing some recent research on the medical fields, and it seems that this may be a high category of what I might want to go to college for. I have learned that through hard work and a strong mental focus, you can succeed in anything. People always dread about what they are goi ng to do with their life, but I have to look at it from a different point of view, I mean when you were a kid it was all about money, but when it comes to doing it your whole life, it’s about what you love to do the most. My post high school plans are attending Blue Mountain community college or Columbia Basin for the first year or two to knock out my Associates Degree. My family has always said I was the smart one, so I want to prove to my family that I can do something better then the ordinary low paying job. Right now there is nothing stopping me from going to college, so therefore I am not worried about what I am going to do, people change their majors all the time, it just comes to show that people end up doing what they love most, and after doing research I feel the most comfortable with studying in the medical field. We never stop learning, each day we learn something new. I want to use the tools I have learned in high school to help me with my medical field study. Peo ple say I am very caring and quiet, which I think would be good in the medical field

How Salt Melts Ice and Prevents Water From Freezing

How Salt Melts Ice and Prevents Water From Freezing Salt melts ice essentially because adding salt lowers the freezing point of the water. How does this melt ice? Well, it doesnt, unless there is a little water available with the ice. The good news is you dont need a pool of water to achieve the effect. Ice typically is coated with a thin film of liquid water, which is all it takes. Pure water freezes at 32 °F (0 °C). Water with salt (or any other substance in it) will freeze at some lower temperature. Just how low this temperature will be depends on the de-icing agent. If you put salt on ice in a situation where the temperature will never get up to the new freezing point of the salt-water solution, you wont see any benefit. For example, tossing table salt (sodium chloride) onto ice when its 0 °F wont do anything more than coat the ice with a layer of salt. On the other hand, if you put the same salt on ice at 15 °F, the salt will be able to prevent melting ice from re-freezing. Magnesium chloride works down to 5 °F while calcium chloride works down to -20 °F. Key Takeaways: How Salt Melts Ice Salt melts ice and helps keep water from re-freezing by lowering the freezing point of water. This phenomenon is called freezing point depression.Salt only helps if there is a little bit of liquid water available. The salt has to dissolve into its ions in order to work.Different types of salt are used as de-icing agents. The more particles (ions) formed when a salt dissolves, the more it lowers freezing point. How It Works Salt (NaCl) dissolves into its ions in water, Na and Cl-.  The ions diffuse throughout the water and block the water molecules from getting close enough together and in the right orientation to organize into the solid form (ice). Ice absorbs energy from its surroundings to undergo the phase transition from solid to liquid. This could cause pure water to re-freeze, but the salt in the water prevents it from turning into ice. However, the water gets colder than it was. The temperature can drop below the freezing point of pure water. Adding any impurity to a liquid lowers its freezing point. The nature of the compound does not matter, but the number of particles it breaks into in the liquid is important. The more particles that are produced, the greater the freezing point depression. So, dissolving sugar in water also lowers the freezing point of water. Sugar simply dissolves into single sugar molecules, so its effect on freezing point is less than you would get adding an equal amount of salt, which breaks into two particles. Salts that break into more particles, like magnesium chloride (MgCl2) have an even greater effect on freezing point. Magnesium chloride dissolves into three ions one magnesium cation and two chloride anions. On the flip side, adding a tiny amount of insoluble particulates can actually help water freeze at a higher temperature. While there is a bit of freezing point depression, its localized near the particles. The particles act as nucleation sites that allow for ice formation. This is the premise behind the formation of snowflakes in clouds and how ski resorts make snow when its slightly warming than freezing. Use Salt to Melt Ice - Activities You can demonstrate the effect of freezing point depression yourself, even if you dont have an icy sidewalk handy. One way is to make your own ice cream in a baggie, where adding salt to water produces a mixture so cold it can freeze your treat.If you just want to see an example of how cold ice plus salt can get, mix 33 ounces of salt with 100 ounces of crushed ice or snow. Be careful! The mixture will be about -6 °F (-21 °C), which is cold enough to give you frostbite if you hold it too long.Gain a better understanding of freezing point depression by examining the effect of dissolving different substances in water and noting the temperature required to freeze it. Good examples of substances to compare are table salt (sodium chloride), calcium chloride, and sugar. See if you can dissolve equal masses of each substance in the water in order to get a fair comparison. Sodium chloride breaks into two ions in water. Calcium chloride forms three ions in water. Sugar dissolves in water, but it doesnt break into any ions. All of these substances will lower the freezing point of water. Take the experiment a step further by exploring boiling point elevation, another colligative property of matter. Adding sugar, salt, or calcium chloride will change the temperature at which water boils. Is the effect measurable?
