Dry Ice: Carbon Dioxide

Dry ice is made up of not only water but also carbon dioxide. We first put the ice in a pan. Then, we put water in the pan and watched fog come up from the pan. It is lower than 0 degrees. As we put more water the fog would expand.

To do this project, you should do research that enables you to understand the following terms and concepts:

Sugar is an additive and should have an effect on the freezing point of water.

The type of cold pack presented here contains ammonium nitrate, which is a white crystalline substance. When these crystals react with water they split into positive ammonium ions and negative nitrate ions. Due to the energy expended by the water in order to dissolve these crystals, the water becomes colder.

Water reaches its maximum possible density at 4 degrees Celsius. This is because, at this temperature, 2 opposing effects are occurring in balance. When water cools down to freezing point, the molecules that usually move past and mix with each other, have less energy and the hydrogen bonding between the molecules takes over. As hydrogen bonds are weaker than covalent bonds, the molecules will no longer be as tightly held together as they were, causing the water to expand as it turns into ice. Ice has an open structure where all of the ice crystals are fairly sparse and spread out with a lot of empty space within the structure. This means that it has a larger volume to mass ratio and thus

Its Chemical formula is CO2. The liquid form of carbon dioxide has to be contained in a very high pressured container and is fit difficult to acquire. Dry ice has a reaction to any substance once it is taken out of its container that, that reaction is called sublimation. Sublimation is a chemical process where a solid turns into a gas without going to a solid state. The most likely reason the speed of sublimation will vary is because of the density and viscosity of the substance. Viscosity is the property of resistance to flow in a fluid or semi fluid (“Merriam- Webster.com”). Density is how packed together something is. Given this information about dry ice and sublimation, the rate of any substance can vary in many ways. Therefore, if dry ice is placed in the thinnest liquid with the least density then it will have the fastest sublimation right because the reaction will happen sooner than a liquid with a higher density and a thinker

As it “melts”, it evaporates to a harmless gas, eliminating puddles of water. Because dry ice starts off as a snowflake, it can be pressed into many forms. The most common form is a large block, but pellet sizes are available for smaller more complex uses. Besides the obvious use for refrigeration, its smoking affect is used in many different applications. A favorite to many is the school project volcano. Where dry ice is dropped into a hot canister of hot water, causing smoke to billow out of the top and run down the sides.

Ice starts as water that has a temperature of any degree above thirty-two degrees Fahrenheit. Before water technically becomes water, which is the name of the liquid state, it starts as a gas called water vapor. After water vapor condenses because of a loss of energy, it is then in liquid phase of H2O, called water, which can then be broken down in the smallest unit; atoms.

If you dropped ice cubes into both a sample of water and a sample of methanol, the methanol would cool faster, due to its lower specific heat. A lower specific heat means that for the same heat change, there will be a greater change in temperature.The assumption that can be made from this is that methanol would not make a good coolant, due to its inability to hold it’s temperature.

Water. Popular to common misconception there is only 1 type of water, misconception being freshwater and saltwater, saltwater is a mixture from churned up sand and salt from the seabed where freshwater is moss and inland (not connected to the ocean in any way) .Water or otherwise known as H2O is includes both chemical and physical properties. Water can be identified in 3 different states of matter, solid, liquid and gas, known as ice, water and steam in order to reach these three states of matter you must allow it to be put under different environmental measures, which is temperature. To make ice water is to be cooled to 0 degrees Celsius and under, for water you must keep the temperature in-between 1 and 99 degrees

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

The first two questions will be answered during the introduction of the lesson and the rest will be the laboratory analysis questions. These will get the students to analyze and make sense of their lab results.

Damon Matthews, a professor in Concordia University’s Department of Geography, found a direct connection between carbon dioxide and global warming. Matthew’s studies show that same global temperature increase, regardless of when or over what period of time the emission occurs. The effect of adding more carbon dioxide is predicted in the theory of greenhouse gases. Swedish scientist, Syante Arrhenius, first proposed the theory in 1896, based on earlier work by Fourier and Tyndall. At the same time, many scientists have reached the same conclusion. If we increase the amount of greenhouse gases in the atmosphere, the Earth’s temperature will increase. Energy is absorbed from the sun in the form of visible light and ultraviolet radiation. The earth then releases some of this energy as infrared radiation. Greenhouse gases in the atmosphere captures some of this heat, then re-emit it in all directions. During this process, carbon dioxide and other greenhouse gases keep the Earth’s surface 33 degree Celsius warmer than it would be without them. According to an ongoing temperature analysis conducted by a scientist at NASA’s Goddard Institute for Space Studies (GISS), the average global temperature on Earth has increased by about 0.8 degree Celsius. Since 1975, two-thirds of the warming has occurred at a rate of roughly 0.15-0.20 degree Celsius per decade.

Imagine a world with no trees, no healthy grass, no glaciers, or no living creatures at all. The cause of this tragedy could be the increase in heat in the Earth’s atmosphere due to global warming. If global warming continues to increase, the world will be left empty. The Earth has been around for a long time, and many feet have walked on it, but no one has walked on this Earth without trees, grass, or creatures. With global warming, the Earth’s meteorology gets too warm, and all of the glaciers will start to melt. Global warming occurs when an increase in the carbon dioxide levels causes the temperature of the Earth’s atmosphere to rise. The Earth’s meteorology is often a subject explored in literature. For example, “Chronicles of Ice” talks
