Science Fair Project : The Freezing Of Water

3.Introduction- In order to do this experiment you must know certain terms and formulas. Molar mass is defined as one mole of this substance. The molar mass is what we are trying to find.One equation use d to find molar mass is MW=m/n. Another thing needed to know is the Ideal Gas Law. The equation used for this is PV=nRT.

To place a reader in the mind of a character, the author must create a scenario which will appeal to the senses, and keep readers intrigued. The technique of building imagery can successfully transform the world around the reader, and connect them to the story. One Mile of Ice by Hugh Garner uses many imagery-building techniques to place readers in the mind of a man on the verge of death. In this story, Hugh Garner tells the tale of two brother-in-laws, Ralph and Pete, who venture off into town, accompanied by mare and sleigh, to get presents for the children for Christmas. However, their journey takes a very dark turn not too far into their adventure. The crisp winds become a blinding storm, in which Ralph and Pete are forced to fight for their lives. Unfortunately, only one man survives - Pete. One Mile of Ice uses visual components to build imagery, as well as tactile techniques to throw readers into the mind of the protagonist. Alongside this, the author uses auditory traits to reproduce the true terror experienced in this story by these brother-in-laws.

In my project, I will do an experiment to find out which material makes ice melt the fastest while the temperature of the room will remain the same. This research is important because if you are short on ice and you need it you can figure out which material will make your ice last the longest if you have no insulation. For example, if you were in the desert and had a cooler you would know what to put in your cooler to make your ice last the longest. I will be testing with three different materials: steel, wood, and fabric. My hypothesis is if the steel retains the ice's cold temperature then it will take the longest for the ice to melt. My goal is to help cooler companies improve their coolers by outlining them with whatever material helps

In order to fulfil the labs purpose, the lab was split into two parts. The first part consisted of measuring and determining the freezing point depression of the solution water. The second part consisted of measuring and determining the freezing point depression of a solution that consisted of water and an unknown solute.

To prepare a quantitative solution, you need to know the weight of the substance and the quantity of the solution. For example, you have 40 grams of NaOH (Sodium Oxide) in 1000mL of water. The amount of water and weight of the substance makes a Mole. one mole is equal to 1000mL of water and 40 grams of NaOH and varies by the amount of water you have but the weight of the substance must also change. To make a correct solution, you need to know the atomic mass of the substance and how much water you have in mL or L. If there are multiple elements, you need to add the combined weight of all elements (EX. NaOH= 23+16+1+40 grams.) and then divide the weight by the mass. To make a solution, you should use a beaker or flask that can measure at least

Despite the hot weather, a big tray of ice was prepared for our children to play, explore, investigate, and keep them cool. They developed the attention and concentration, practiced their hand-eye coordination and fine motor skills trying to catch the slippery ice while secretly strengthen the muscles in their fingers as well as used their senses of touch, taste, and sight to learn the ideas about wet, dry, slippery, and sloppy.

why wont water freeze if you put ice in it, despite ice being frozen?and is it a physical or chemical thing?

We have found that the (salted) ice water bowl cooled the can of soda to a good drinking temperature of about 44 degrees after about 5- 6 minutes. The can in the freezer should have only reached about 60 degrees or so ,it needs a good 20 minutes to get nice and cold .And that is because the salt lowers the freezing point of the water in the bowl ,allowing the ice in the ice bath to melt while still retaining its temperature. This makes the cold water in the ice bowl even colder .The freezer, while it is pretty much cold, just didn’t make the competition because cold air just isn’t enough to do the job quickly. Water is a much better heat conductor than air, so heat is able to leave the can more quickly in the ice

Molar concentration is simply the number of moles of ions per liter of water. Parts per million is a ratio of weights, and for every one part per million, there is 1 pound of solute for every million pounds per liter. (Hardness)

If I add salt to one of the bottles of water, but not to the other, then the bottle of water that had the salt will take longer to reach its freezing point.

During the first plateau, where the temperature stayed at 23° between 2 and 3 minutes, was when most of the ice had started to melt, but there were still ice in the beaker that had not melted yet. The remaining unmelted ice kept the temperature level by keeping the water cool for a minute because it took a minute for the rest of the ice to melt away, before the temperature rose again. In this stage, in order for a solid to melt into a liquid, it must be warm enough. When it is warm enough, the atoms that make up the piece of ice starts getting energized due the heat. The atoms eventually become so energized that they slowly start to change into a liquid again, since ice is made out of water.

My Science teacher got dry ice and put in a little plastic tray and an aluminum tray. Then she added water to the tray and the dry ice started to react with the water. Very quickly the trays were getting very cold. It started to let out this sort of fog and it was floating down.

The witness has been the manager at the Ice Rinks for the last 4 years. He reviews ice contracts and is only involved with the interior portion. He reports to Gart Snow who is the general manager of the New York Islanders and employees. Other employees who make up the team and shoveled the snow are Scott Berge, Joseph Fin, Richard Glass and Jimmy Carumma. The work was directed by the witness. The assistant manager is Christina Mott. There are approximately 40 cars in the parking lot, in front of the building and about 10 cars in back of the building.

Salts are used in many different environments and for many different reasons. One common purpose that most people know of is the use of salt on the road to help the roads not freeze over in the winter. People use salt for things like this because salt has the ability to lower the freezing point of the water. This happens because the salt dissolves in the water and the moving water molecules begin to “melt” the ice. Since there are molecules of solute in the way, the formation of the ice crystals begins to become more difficult and happen less frequently. (Senese). The same process happens when salt is added to the ice to freeze the ice cream mixture. When creating the ice cream, this same process happens. The salt lowers the freezing point
