This experiment will be highlighting the significance of atmospheric pressure in a cloud`s formation. Clouds form when warm, moist air rises in the atmosphere. On its way up, it cools so that the water vapor condenses into small particles such as airborne dust, thereby forming water droplets. This is exactly what a cloud is, a large collection of very tiny droplets of water or ice crystals. This process is known as cloud formation and is affected by temperature since clouds are occasionally produced by the mixing of warmer and cooler air currents. This process is part of the water cycle which is the transfer of water from air, sea land and water in a cycle. Overall, this paper will be explaining the materials and methods that will end up …show more content…
If a cloud is water vapor, and vapor has weight, why does it float in the air? Well, according to columnist Adams, “a modest-size cloud, has a mass equivalent to one B-747 jumbo jet,” but the cloud`s mass is spread over a big volume of space which causes the density of it to be relatively low. Furthermore, the process of condensation is essential to the water cycle since it is responsible for the formation of a cloud which creates precipitation that allows water to return to the planet`s surface, thus letting the cycle to continue. In order to form a cloud, there are three requirements which, according to Oklahoma Project, are essential. First, water vapor must be present in large amounts. Secondly, cloud condensation nuclei such as dust or salt particles must be present in order to provide a basement for water to condense. Lastly, a cooling mechanism must be present to cool the air temperature to a certain point, allowing clouds to form.
Based on all these information, my specific question that I hope this experiment answers is: What role does air pressure as well as temperature plays on the biological process known as cloud condensation? My hypothesis consists of understanding these factors. “If water vapor attaches to particles such as smoke, together with a specific temperature, then the process of condensation will allow a cloud to be formed.”

Dry ice is a solid form of carbon dioxide that produces a cold dense mist. I first learned what Dry Ice was in fifth grade, this was due to the fact that my class had taken a field trip to River Legacy Park. Where we saw an experiment and learned facts about dry ice. This led to a fascination with dry ice, in this experiment I will test whether the temperature of water and soda affect when poured over Dry ice. Dry Ice has multiple purposes some of which, is chemotherapy, to carbonate liquids, store food, and accelerate plant growth. Since, I always liked the thought of working with Dry Ice I had begun to think of an experiment to do for the IA involving Dry Ice. After much consideration I choose to test how soda and water would
Clouds to form in the atmosphere have to have water vapor present. This water vapor makes up a cloud. The water vapor in the atmosphere comes from evaporation or deposition. Also the temperature of the air is below the dew point. When the water is fully saturated, it starts to rise and the expansional cooling process begins. During the process of condensation, the aerosol particles act like a nuclei in the atmosphere, which began to grow, creating ice crystals that are big enough to produce a cloud.
Condensation is the opposite of Evaporation. It is when saturated air cools down below the dew point which causes them molecules to stick together and from clouds. When we see clouds they don’t all look the same. This goes back to when the temperature causes the amount of water to evaporate. So that’s why clouds are all different shapes and sizes.
Clouds- Clouds are a mass of water or ice droplets in the air. An example of a

In this document, I jotted down some notes while putting together the reading material. These notes point out some of the reading content to pay particular attention to. The notes are divided into section headings based on the reading material. This is not meant to be a complete list of everything that you need to know from the reading Water in Atmosphere You should know what is meant by phases of water and phase changes of water. Water vapor is extremely important in the atmosphere for many reasons. A few of those reasons include Water vapor transforms into both liquid and solid cloud particles that grow and fall to Earth as precipitation. When water vapor condenses in the formation of clouds, large amounts of heat - calledlatent heatis
The purpose of this experiment is to investigate some physical and chemical properties of gases and to use these properties to identify these gases when they are encountered.
Condensation As the evaporated water vapor gets colder rising into the atmosphere, it changes back into different levels of liquid clouds of different types.
The purpose of this experiment was to test and observe the physical and chemical properties of gases, and to use these properties to identify these gases when they are encountered.
The water cycle is an ongoing process where water is constantly being changed from a liquid to a gas and back to a liquid. The water that is on the ground is evaporate into a vapor into the sky. Once the vapor is in the sky it condense and forms clouds. The cloud collect as much water as they can until, the water becomes too heavy and release the water back unto the ground. Then the whole water cycle the starts all over again.
The one candle got the water to rise up 1 inch and a half, two candles rose ¼ of an inch and the three candles got the water to rise up ¼ of an inch as well. Because of the results it was hard to match it with an explanation but the closest it supported was explanation 3 because of the water still rising a bit than nothing. Since more candles mean more carbon dioxide being created we came to conclude that there might have been CO2 molecules dissolving in the water causing it to rise a bit. The experiment disagreed with explanations 1 and 2 because there was no pressure in the outer of the flask to cause the water to rise up and the water barely rose which causes it to be that what should have caused the rising was the CO2
In this lab, the experiment focused on the relationship between the temperature and pressure of an ideal gas that was dry ice inside the closed container. Therefore, the volume remains constant because the ideal gas was in a closed container.
The procedure for this experiment was to first obtain four balloons and blow them up in order to stretch them. Then obtain and fill the four large test tubes each with thirty milliliters of warm forty degrees Celsius water and two grams of dry yeast which was weighed on a scale and scooped out by a spatula. After five milliliters of water, ten percent glucose, fructose or sucrose went into one of the four test tubes. Then parafilm was placed on top of each of the test tubes to seal them and they were swirled activating the yeast through rehydration. After swirling the film was removed and the balloons were tightly placed on the test tubes. Then finally observed the tubes build up of CO2 all the while swirling gently every fifteen minutes, recording observations.
‘Low pressure atmospheric systems have more of a short term impact than high pressure systems.’ Discuss.
It's on the last part of your question. The rate of evaporation is whats changing. When a liquid sits in one place and its molecules turn into a gas, Then it's called evaporation. No matter how cold or hot it is, it can still evaporate. When matter has a high energy then the water molecules have a high energy too and go through a change. Evaporation focuses on individual molecules and not on the amount of energy. The energy can be low and still evaporate. Not all liquids are the same. There are some that evaporate faster in wind. When liquid molecules move around, They bump into each other. When they do bump into each other then one molecule gains energy and one loses energy. If one molecule gains enough energy then the molecule can turn into a gas. In other words, it has evaporated.
