An Article On Turning Water

Maria’s hypothesis for this experiment is that the cold water will freeze faster, she thinks this is correct because the hot water molecules move faster than the cold water molecules, causing the hot water to take longer to freeze.

After taking the mass of water and combining a “dry ice pellet … the mass of the water in the cylinder is less than… at the beginning” (644). More experiments were completed with various

After 5 min passed the plastic container created a thin layer of ice surrounding the container.

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

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

Taking ice cream outside on a warm day and then on a cold to see if warm weather affects the melting of ice cream would be the experimental approach.

The first part of the lab began by one lab member adding 10.0 mL of DI water to a test tube while another lab member obtained a beaker full of ice and salt. After both these steps were complete the test tube was put in the beaker full of ice. Immediately following the test tube be being placed in the beaker, a temperature probe was inserted into the test tube. The initial temperature was recorded and after the temperature was recorded in 30 second increments. Once the water exhibited supercooling and then remained consistent at .1 °C for 3 readings it was determined that the water had froze and formed crystals. Evidence that crystals formed allowed for it to be confirmed that the water actually hit freezing point at .0

The objective of this experiment is to test the melting point of ice against different variables. I will use a control of ice against air and test this next to ice in water, sugar on ice, salt on ice and Baking Soda on ice. By measuring the melting time of each element on an ice cube I will be able to tell which element affects ice’s melting properties at what rate.

The experiment will start with two ice cubes. One will have nothing added to it, the other will have ½ tsp of salt sprinkled over it. Each will be separate on two different plates/containers. Time will be kept with a stopwatch, and notes will be taken throughout the experiment on the percentage of ice that has melted at certain points in time.

2) When water freezes there are additional hydrogens bonds formed between molecules and those molecules become slow.

1. First, 3.0015 g of salicylic acid were measured using an electronic balance. 2. The salicylic acid was then transferred into a 150 mL beaker.

Get 2 basins, fill one with iced cubes and water, and fill the other one with warm

A team member might have been rushing while she was reading the mass. Lastly, this experiment taught the lab how to observe the temperature of ice and water during the constant addition of heat, use logger pro probes and software to collect and analyze the data and most importantly, observe graphically the temperature data as the ice melts, water warms then

Would salt, sugar or sand work better? Background research III. Ice begins to melt when its temperature exceeds 0 degrees Celsius and hydrogen bonds between water molecules break.

water should be cold enough to freeze over, but it surprisingly never does(Berke 10). In
