Cloud Often Seen In The Summer 2008 / Isotopes Lab Answer Key

Kelvin-Helmholtz clouds are rare – the only time I spotted one was over Jutland, western Denmark – because we can only see this process taking place in the atmosphere if the lower air mass contains a cloud. Many satellites orbit the planet in the thermosphere. So, a lower temperature makes the air less able to hold water vapor, which leads to condensation. Altocumulus clouds are often called "sheepback" or "mackerel sky" because they resemble the wool of sheep and scales of mackerel fish. Congestus – Very tall, puffy clouds that look a lot like a head of cauliflower. If you're a fan of weather folklore, you've likely heard the above sayings, both of which are true. One of our personal favorite clouds, mammatus clouds are a stunning cloud formation that you'll sometimes see ahead of a thunderstorm. Cirrus clouds usually form when the weather is nice. Retrieved from Oblack, Rachelle. " Although every instance of cloud formation is different, chances are pretty high that one or more of these four processes are involved whenever you see clouds in the sky. Breadcrumb SkySci for Kids Clouds and Raindrops The Cloud Gallery Click a cloud name below to jump to that cloud type or scroll through and take a look at them all. The name Nimbostratus comes from the Latin words nimbus which means "rain" and stratus for "spread out". Also known as a flammagenitus cloud, pyrocumulus clouds are a relatively rare type of cloud.

Praecipitatio – Any cloud with precipitation that's actively reaching the ground. If the mammatus are far off and not approaching, you may be spared experiencing the storm. Commonly called nacreous clouds or mother of pearl clouds, these clouds form in the stratosphere from about 6 to 15 miles (10 to 25 km) above the Earth's surface. Near the ground, Cumulonimbus are well defined, but higher up they start to look wispy at the edges. This is common in the summer, with morning Cumulus developing into deep Cumulonimbus (thunderstorm) clouds in the afternoon. Nebulosus – A highly uniform cloud with no distinct details, cloud tufts, whisps, or other features.

Aircraft avoid flying at the altitude at which lenticulus clouds form. Supplementary Features & Accessory Clouds. They form as the water vapor in the atmosphere condensates around the particulate matter coming out of the aircraft's exhaust. Opacus – Very thick layers of clouds that block out much of the sun behind them. There are two main ways to reach a point of saturation. But it can overshoot, in which case the air mass bobs back up allowing another Lenticular cloud to form. They're some of the simplest clouds to identify, especially since they look like balls of cotton stuck into the blue background of the sky.

Spissatus – Fine, wispy clouds that bunch together into dense collections, sort of like a feather. These tiny particles are called "condensation nuclei", and they allow condensation to happen when the air has reached saturation. When altocumulus appears with another cloud type at the same time, a storm normally follows. Stratus cloud is thin, so while conditions may feel gloomy, rain is unlikely, and at most will be a light drizzle. If you see these clouds on a warm summer morning, a thunderstorm might happen by late afternoon.

So, these clouds are nice to look at and they usually don't indicate any incoming severe weather. They are usually seen over the northern horizon from northern hemisphere locations, though they can extend over more of the sky around summer solstice in June. This is why this cloud is common in the winter near the Great Lakes. Cumulonimbus capillatus – The top-side of the tower cloud is fibrous. You'll generally find mammatus on the base of cumulonimbus clouds, but they're usually only visible for about 10 to 15 minutes at a time. There is no clear-cut boundary between the layers of the troposphere and these layers will fluctuate based on prevailing atmospheric conditions. It's the most recognizable out of all the types of clouds. Related: What's in the night sky this month?

Jan Remund Clouds that Make Rain and Snow Nimbostratus Clouds Nimbostratus clouds form a dark gray, "wet" looking cloudy layer associated with continuously falling rain or snow. Cirrostratus: Thin white clouds that resemble veils that tend to cover the whole sky. Frontal: A mass of warm air rises above a mass of cold, dense air. These clouds form due to convection and daytime heating. They're quite translucent which makes it easy for the sun or the moon to peer through. If you see big fluffy clouds overhead, you're probably looking at cumulus clouds. The tops of cumulonimbus clouds are always shaped like an anvil or a plume.

So, if you see these clouds, severe weather might be on its way to your location. Altocumulus in Weather Folklore Mackerel sky, mackerel sky. They look like a fog that wraps around the horizon (instead of the ground). Overall, there are three different types of clouds: high, middle, and low.

Share or Embed Document. Ideally, at least one of the types of beans should be substantially different in size from the other types so students have a visual cue that not all beans (isotopes) will have the same mass.

In the following instructions, Table 1 is for Method 1, Tables 2 − 4 are for Method 2, and Table 5 is for Method 3. One thing we want to point out is that atomic mass or atomic weight is the average mass of 1 mole atoms with a unit of g/mol; but in this experiment, it is the average mass of 1 atom (1 bean) with a unit of g. ACKNOWLEDGEMENTS. Isotope practice answer key. Iron-55: netics (DNA research). This experiment is originated from the "Bag O'Isotopes", [1-3] in which small numbers of "isotopes" (e. g., 8 large lime beans, 11 baby lime beans, and 15 black-eyed peas with given atomic numbers) are presented to students and they count all of the isotopes to find the atomic mass of element "legumium". The atomic mass of legumium can also be determined by finding the mass of the entire sample and dividing by the total number of isotopes in the sample. The larger the sample sizes and the better mixed the beans, the closer the results should be. This lowly research chemist has brought this new element to your classroom so that the lab technicians can determine the atomic mass of Beanium. Phosphorus-32: blood cell studies.

Enter the data in Table 4. Before the activity, mix together three different types of bean in a large bowl. All atomic masses agree with the relative masses to three significant figures. To do this, completely separate all of the legumium atoms into three isotopes: white beans, red beans, and black beans. The statement that the atomic mass of chlorine represents the mass of the most common naturally occurring isotope of chlorine is false. Other beans or peas can also be used; different beans with similar size and round shape are recommended to simulate isotopes of one element. © © All Rights Reserved. An apparatus for separating isotopes, molecules, and molecular fragments according to mass.

If the lab reports are not satisfactory, the instructors may take extra efforts to address all of the problems (highly recommended) so that the students can build a solid foundation on experimental data treatment. Document Information. This is a custom bundle created for Lana. This mass ratio insures that when we weigh beans in this mass ratio, we must obtain the same number of beans. In general, 70% – 90% students can get the experimental results within the average deviation. Although the definition is simple, we found some students (mainly high school students and non-science majors) still cannot fully understand this abstract concept after profound lecture teaching. Calculate the average atomic mass from Step 2 (Table 1). 100-mL beaker or plastic cup. With the three methods and the large number of beans (to reduce the measurement errors in Method 1), the students then can do rational statistical calculations of their experimental results and analyze their experimental errors.
