5. Record the data in a chart with the times. Experiment Basically the experiment is on what household items can insulate and hold the circulation of cold air inside the ice box which allows freezing points or melting points to take course. Data/ Graphs Ice Boxes | Test 1(none) | Test 2 (salt) | Test 3(Sugar) | Cardboard | 7:14.8 | 12:52.7 | 8:35.2 | Paper | 9:28.4 | 12:14.8 | 7:43.6 | Aluminum Foil | 16:35.1 | 17:21.6 | 13:17.8 | Time Graph Observations When I experimented I noticed that one of the ice boxes melted quickly than the others, which could mean that those ice boxes vents heat. The substance added to the ice box could have either helped it stay cool or melted it quicker.
Let’s find out! Dry ice is known for common Halloween tricks, but that’s not all there is. Dry ice is a solid frozen form of carbon dioxide. Dry ice is 1.5 times as dense as air ("Dry Ice." How Products Are Made.
11.2 Particulate Model for Solids, Liquids and Gases A block of ice Solid molecules have a restricted motion = Solid A beaker of boiling water Gas molecules are able to move at extremely high speed = Gas A beaker of warm water liquid molecules have greater mobility = Liquid States of Matter Solid * In solids, the molecules are arranged close together in a regular pattern * Strong attractive intermolecular forces hold the molecules in position so they have definite shape and volume * They can only vibrate in their fixed positions Liquid * In liquids, the molecules are not arranged in a regular pattern and are slightly further apart then those in solids * The attractive intermolecular forces are not very strong. Thus, the molecules are able to move among one another, giving liquids its definite volume but not a definite shape. Gases * In gases, the molecules are widely spaced. Intermolecular forces are negligible * The molecules move about randomly with high speeds, colliding with the walls of the container, occupying any available space. Research on *phase changes for water* Heating curve (Please!!!!!!
When there’s no magnet around, ferrofluid acts like a liquid. The magnetite particles move freely in the fluid. But when there’s a magnet nearby, the particles are temporarily magnetized. They form structures within the fluid, causing the ferrofluid to act more like a solid. When the magnet is removed, the particles are demagnetized and ferrofluid acts like a liquid again.
As a result of glaciers tends to float toward the outside using the pressure of its own weight. The process of this advancement is called glaciations. Glaciers also help us maintain our water supply as well as the ocean’s level variation. Glaciers also enlarge and are reduced, depending on the changes in our weather. Some people think the melting of the glaciers are results of global warming.
According to Merriam-Webster’s dictionary, the definition of snow is, “precipitation in the form of small white ice crystals formed directly from the water vapor of the air at a temperature below 32 degrees Fahrenheit.” Whereas, rain is defined as, “water falling in the drops condensed from vapor in the earth’s atmosphere.” There are many similarities and differences to rain and snow because of formation, destruction, weather apparel, and kids enjoyment. Another similarity between snow and rain is that they can both be very destructive. Large amounts of rainfall can produce floods. Floods can destroy homes, ruin farmer’s crops, and even loss of human life. Treacherous rainfalls are also able to produce landsides.
However, with a global rise in temperatures, the storage of water is shifting, especially for the water locked in permafrost, and other glaciers. (greenfieldgeography, 2014). Much of the water locked in ice is from icebergs, and shelves, which are already part of the ocean in terms of volume, and so their melting actually does nothing to the overall volume of water, although ice is less dense than water is, hence, as the ice melts it does not take up larger volumes of space. The main reason for this change in water storage is the shift in global temperatures, due to climate change. A huge issue is the rising of sea levels, due to the increase in global temperatures.
Unlike dry deposition, winds can blow wet deposition hundreds of miles away from the source of emission, making it an issue for everyone. Natural, unpolluted rainwater is slightly acidic, with a pH of around 5.6 due to a natural occurrence of CO2, NO and SO2 substances. Therefore a pH value less than 5.0 is considered to be acid rain. In certain areas of the United States, the pH of rainwater has been measured
It is a special type of polyethylene plastic that allows the board to have a minimal friction coefficient when sliding down snow-covered ground, creating a "slippery" feeling. This plastic was designed to absorb wax for conditioning and extended life. A steel ring (7) serves two purposes: it protects the sides of the snowboard and puts maximum force into the snow for optimum maneuverability. The graphic layer (2) is a printed layer of fiberglass giving the snowboard an appealing design. There are literally millions of different snowboards with a unique graphic on them, but snowboard consumers may have a custom
Due to the increase in greenhouse gases less solar energy is reflected back into space and more solar radiation is absorbed by the Earth causing the increase in ice and snow melting (Main & Ahlenius, 2011). With this background information the change of climate conditions such as, snow, rain, winds, and temperature is continuously happening all around the world and will continue to worsen in the future. A good indication of climate change is to look at the melting of glaciers and the Polar Regions as the Arctic is one of the fastest warming regions of the world. However, since the Polar Regions are so big and cold it would be impracticable for humans to live and carry out research there. Therefore, by using applications of remote sensing we can easily observe inaccessible areas from satellites to effectively monitor and map snow and ice cover in Polar
