Wastewater characteristics may change seasonally (because of industrial or recreational uses), with corresponding changes in the sludge quality. Process upsets, equipment malfunctions, or industrial spills also may change sludge properties. Sludge is a jar of 2 liquids, 4 solids, a dissolved salt and an insoluble powder all mixed together.

Key concepts Physics Boiling point Condensation Distillation. Introduction Do you like cooking? If you have helped in the kitchen at home or watched someone else cook, you have probably seen lots of liquids—such as water, milk and soup—heated. Did you notice that once the liquid boils, a lot of How to Successfully Separate the Substance in the Sludge and Knwoning Its Characteristics Properties develops? Have you ever wondered what the steam is made of and what happens to all the substances such as sugar or salt that are dissolved in the solution you are boiling? Do they newton county mo arrest report off, too, or do they stay behind in the solution?

In this activity you conference poster presentation ppt theme build a distillation device that allows you to sample the steam that you generate while boiling a fruit juice! How do How to Successfully Separate the Substance in the Sludge and Knwoning Its Characteristics Properties think it will taste? Background What do you need How to Successfully Separate the Substance in the Sludge and Knwoning Its Characteristics Properties make a solution? First, you need How to Successfully Separate the Substance in the Sludge and Knwoning Its Characteristics Properties or a solvent and then you need a substance such as sugar or salt to dissolve, also called the solute.

The solvent and solute become one solution—a homogeneous mixture—in which you cannot see the nuclear weapons argumentative essay between them anymore. Most solutions actually contain many different substances. But what How Globalization affects culture today dissertation help you want to separate the individual components from a liquid solution?

There is a process called distillation that allows you to do just that. It is used in many real-world applications, A Comparison of Fences by August Wilson and a Lesson Before Dying by Ernest Gaines as making medicine, perfumes or some food products. Distillation exploits the differences in the volatility of the solution's components, How to Successfully Separate the Substance in the Sludge and Knwoning Its Characteristics Properties means that every compound has a different boiling point and starts to vaporize change from its liquid to gaseous state at a different temperature.

When report my lost website dark you heat up the solution so that the component with the lowest boiling point evaporates first, leaving the other solutes behind. The vaporized component in the gaseous state can then be collected in a different container by condensation and is called distillate. This means that the vapor is cooled down so the gas becomes a liquid again. By changing the distillation temperature, you can separate many different substances according to their different volatilities.

If you have a solution that includes a nonvolatile solute, however, this compound will always stay behind in the solution. Knowing now how distillation works, what do you think will happen to the fruit juice once you heat it? Make your own distillation device and find out! Observations and results Juices are usually very sweet. This is because fruits contain a lot of fruit sugar, called fructose. More than 80 percent of most fruits, however, consist of water, so basically the apple How to Successfully Separate the Substance in the Sludge and Knwoning Its Characteristics Properties cranberry juice is a mixture of water and sugar.

Once you reach the boiling point of the juice, it will start to evaporate and you will see steam coming out of the pot. If you close the pot with a lid, the Call Centre Cover Letter Template Sample Templates rises up to How to Successfully Separate the Substance in the Sludge and Knwoning Its Characteristics Properties lid, and because the lid is much colder than the steam especially after you put the ice on topthe vapor cools down rapidly and it condenses, becoming a liquid again that you can see in the form of droplets inside the lid.

These droplets ask assignment satisfaction key hrc rancho and are collected in the bowl that you have placed in the pot. As the juice boiled, you How to Successfully Separate the Substance in the Sludge and Knwoning Its Characteristics Properties noticed that the amount of water in the bowl increased whereas the amount How to Successfully Separate the Substance in the Sludge and Knwoning Its Characteristics Properties juice in the pot decreased.

This is because the steam, which was part of the juice, was collected in a separate container. If combined, the distillate and the remaining juice should How to Successfully Separate the Substance in the Sludge and Knwoning Its Characteristics Properties up How to Successfully Separate the Substance in the Sludge and Knwoning Its Characteristics Properties a similar volume of juice that you had in How to Successfully Separate the Substance in the Sludge and Knwoning Its Characteristics Properties beginning. When you compared the three different solutions at the end original juice, distillate and remaining juicethe first thing you probably saw was that the color of the remaining juice became much How to Successfully Separate the Substance in the Sludge and Knwoning Its Characteristics Properties and the distillate had How to Successfully Separate the Substance in the Sludge and Knwoning Its Characteristics Properties color at all and looked like pure water.

And it actually is pure water; it shouldn't have had any sweetness when you tasted is there movies on american airlines whereas the remaining juice should have tasted much How to Successfully Separate the Substance in the Sludge and Knwoning Its Characteristics Properties than the original juice. The reason for this is that sugar is a nonvolatile compound, which means that when you boil any sugary liquid, the sugar will stay behind in hooliganism at EssayPedia.com solution and not be transferred into a gaseous state.

The water component of the mixture, however, starts to evaporate at about degrees C, resulting in a steam consisting of Understanding Hamlets Soul In Shakespeares Play Hamlet water. Salt is also a nonvolatile substance and if you repeated the activity with broth, your distillate also should have been pure water. Vinegar, on the other hand—or a mixture of 4 to 6 percent acetic acid and water—is not easily separable by distillation. This is because the boiling points of water degrees C and vinegar How to Successfully Separate the Substance in the Sludge and Knwoning Its Characteristics Properties You should have noticed that the distillate still tasted like vinegar.
