Melting point

Does rock salt effect ice? Rock salt effects the boiling and freezing point of ice. Salt has always helped the roads when it is icy in the winter, but a new idea for the roads may be the use of beet juice. In group A with the little bit of ice and water, that we continued to stir, the temperature decreased from 2°C to .5°C in five minutes. In group B, 10 grams of rock salt was added to the ice water and stirred. The temperature of the mixture decreased from -1°C to -6°C in five minutes. After…

Terms that will be discussed in this paper will include freezing point, Phrases of matter, freezing point depression, and solution. Freezing point is the point when water turns into ice (What Makes Ice Melt Fastest). If you have ever lived in a cold climate, you have most likely have seen trucks that put salt and sand on the streets after a snowfall to prevent ice from building up on the roads. Salt acts to the lower the freezing point of water, and changing the phrase of matter. The water is…

might be slush. In this project/experiment we will be determining if the mixture of water and salt will cause freezing point depression once frozen-or almost frozen.When it snows, people throw salt on the ground. The reason why they do that is to prevent ice from forming. The reason why ice doesn't form is because salt lowers the freezing point of the snow/water. The freezing point loses heat so the temperature drops and the molecules begin to move more slowly.Freezing…

Summary The study tested if EKG and core temperature would increase when you placed ice (down your back and in your hand) further from your body’s core. The outcome of the study was that your bodies EKG and core temperature decreased when placed further away from your body’s core. The significance of the study is that it shows people that if you place colder objects further from the core of your body, your vital signs are more likely to decrease, furthermore, the study presents an interesting…

Chowdhury Last four digits of ID#: - 2148 CHEM 26200 -4PS- Mr. Haoran Zhao IDENTIFYING THE PURITY OF A COMPOND USING MELTING POINT AIM The purpose of this lab is to identify unknown compound by measuring melting point.

After the extraction, recrystallization, and determination of melting points for the unknown compound #4 were performed, and observations were noted, the results were obtained. The two compounds yielded were 4-tert-butyl phenol and triphenylamine. The masses obtained of each compound were 0.071g and 0.298g. The melting point ranges obtained are as follows; for the first the solid started to melt at 94 ˚C and was completely melted at 98˚C, and for the second the solid started to melt at 115 ˚C…

what if there was another method that was more environmentally and financially friendly. My project will benefit the town, the government, and the people. Through a chemistry experiment, this project will test how different substances affect the melting speed of ice. The experiment will be testing the effects of salt, sugar, brine, sand, and nothing on the speed at which ice melts. If the substance poured is salt, then the ice will melt the fastest. This is because salt lowers the freezing…

I was born on September 1st 2001, I was a happy baby ready for the world to come. I was a very energetic I always wanted to know what was happening. Some of my favorite memories of me with my family were (and still are) the long road trips we do to San Diego. Also I really enjoyed flying to Connecticut to see my mom's side of the family. In the Hollister history the best road trip was when the car broke down just before the Grape Vine ( it is a big hill just before LA). We had to pull over and…

and pedestrians. Icy roads and sidewalks can become very hazardous for travel. A solution must be implemented to mitigate risks associated with winter travel. This problem is relevant to the experiment since I will be testing different methods of melting ice. The solution resulting from the experiment can be used throughout the world to make our roads safer. The literary reviews for this experiment are from two different sources, which both identify problems and potential solutions that…

difference in freezing point of the pure solvent and the solution with the unknown solute. This lab will show case one of the colligative properties of a solution. This property is dependent upon the number of solute molecules or ions and not the identity or chemical property of the solute. A common example is water which both freezes and melts at 0°C no matter the amount of water or the size of the ice chunk. The freezing point depression phenomenon refers to the decrease in freezing point of…
