Shocking a swimming pool is the process of adding a large dose of chlorine to the water, killing any bacteria and bringing the pool's free chlorine levels up into the desired range. Shocking a pool also kills any algae that may be growing in it. The shocking process itself is simple, but you need to know when and why to shock your pool as well as how. When to Shock There are two types of chlorine in your swimming pool. The first is free chlorine. Free chlorine is essentially the fresh chlorine…

Climate change is clearly evident in the world around us and it is having and will continue to have a major impact on our lives. Therefore, it is very relevant to analyze the changes in climate that have occurred in Howard County, Maryland such as the significant changes in mean precipitation and timing of precipitation, winter temperature and the summer precipitation. Furthermore, it is crucial to understand that many of these changes will be clearly seen in the relatively near future if…

How does changing the purity of water affect how fast it snap freezes? That’s a good question, but there’s a lot of science to it. Snap freezing is very simple, and easy to do. But to snap freeze, you will need to know about supercooling. Supercooling pure water would always work best. Anyone can purify water, because it’s so simple. You can extreme supercool water into something called a “glass”. You can also bend freezing points, and make them lower. There are a lot of records, physics, and…

The light extinction method was developed based on the works of Piere Bouger, August Beer, and Johann Heinrich Lambert (1760). Bouger observed for the first time that the light intensity of a candle decreases when it passes trough a transparent medium and appointed the length and the medium property as the main parameter to explain the light extinction. The correlation of absorbance and light path was proposed by Lambert. Finally, Beer concluded that absorbance is also proportional to the…

According to appendix 1, the Boiling Crab’s menu has a limited number of foods and beverages, so the existing customers may feel bored after eating them for many time. Therefore, I think the owner should add a seasonal menu to draw the attention of these customers. To illustrate, the Boiling Crab should have drinks with the special dish during spring, summer, fall, and winter. In summer, the fresh coconut juice imports from Thailand, and the seafood with special sauce comes from Vietnam.…

The purpose of this experiment was to find the affect of salt on the temperature of boiling water. Each time I added more salt the temperature was higher than the last one. From the data I collected it shows that the more salt you add the higher the temperature. If you add salt to boiling water the temperature will increase. The data collected shows that my hypothesis was correct because the average number of the different amounts of salt was higher than the last one. Water boils when the…

What is boiling point elevation? How might this have affected your results? Boiling point elevation is the event in which the boiling point of a liquid becomes higher because of an added compound. Ultimately, the boiling point of the solution obtains a higher boiling point than a pure solvent like water. For the lab that was conducted, the solvent that was used was tap water and that itself contained numerous minerals dissolved in it and a variety of chemicals. Boiling point elevation is…

for a substance to transform its state from liquid to gas given an amount of pressure. 3. Why does a steam burn do more damage than a burn from boiling hot water? (Note: Even for the case where water and steam have more or less the same temperature) - Steam burn creates more damage than boiling hot water because it possesses more heat energy than boiling water even if they are at the same temperature. 4.…

trends in physical properties of organic compounds such as boiling points and melting points can be deducted from their structures, including size (molecular weight, surface area), shape and functional groups. These factors significantly influence the strength of the intermolecular forces of attraction present; and the nature and strength of intermolecular forces determine the variations in boilingpoints of organic compounds. The boiling point of a liquid is the temperature at which its vapor…

distillation was first used to separate the unknown mixture into its components based on boiling point. Distillation refers to the method of separating components of a mixture through heating and cooling. Simple distillation, which is especially useful in the separation of less-volatile substances from volatile substances, such as sugar from water, can be used to separate a liquid-liquid mixture if the boiling points of the component liquids differ by more than 40-50°C. A plot of temperature…
