Investigative Question Does sugar or salt effect the freezing point and period of time that water takes to freeze? Hypothesis If you add either sugar or salt to water it will affect the freezing point of the water and will therefor take longer to freeze. Aim The aim of the project is to prove whether or not adding sugar and salt to water will affect the freezing point of the water and will therefor take longer to freeze. Variables Independent Variables: the independent variables are the amount…

snow. First and for most the earth’s surface temperature has to reach the freezing point of 32 F. This lets us know that anything type of precipitation will freeze once it hits the ground. If the temperature between the clouds and the surface is above freezing the precipitation that falls will be rain instead of ice or snow. Rain only turns into freezing rain when the surface of earth is below freezing. If it is not below freezing…

works. 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…

9.Cases and spoilage type due to temperature and time abuse: 9.1.Refrigeration and freezing: Refrigeration slows down the chemical and biological processes in foods and the accompanying deterioration and the loss of quality. The storage life of fresh perishable foods such as meats, fish, fruits, and vegetables can be extended by several days by cooling, and by several weeks or months by freezing. For example, fruits and vegetables continue to respire and generate heat during storage; most foods…

The Mpemba Effect The Mpemba effect is a rather unusual physical phenomenon where hot water freezes faster than cold water, under certain conditions. Intuitively, this doesn’t make any sense. How could water of higher temperature reach freezing temperature quicker than water of colder temperature? Water freezes when it’s molecules lose energy and slow down enough to stick together, forming ice. The molecules of water of high temperature have more energy the molecules in the colder water. So,…

Alaskan Frog does just that! It freezes for seven to eight months, thaws out, and then hops away (“Los Angeles Times”)! Its amphibious body stays about the same temperature as the surrounding air, allowing its internal body temperature to fall below freezing (“Los Angeles Times”)! Research says that wood frogs tracked in the wild proved able to endure below-zero temperatures for as many as 218 days straight with a 100 percent survival rate (“The Truth”). Wood Frog tissue and cell research are…

Freezing and crystallization are linked in that both processes involve initial nucleation followed by crystallization. Sonication is thought to enhance both the nucleation rate and rate of crystal growth in a saturated or supercooled medium by producing a large number of nucleation sites in the medium throughout the ultrasonic exposure. Two main theories which explained the mechanism of nucleation are Hickling theory and molecular segregation theory. Among two theories Hickling is most commonly…

strawberry whole?Reader Question: Can you freeze whole strawberries? Will they turn out mushy when defrosted? Answer: Absolutely! Freezing strawberries whole is my preferred method to freeze strawberries for smoothies. Summer strawberries are always sweeter than what you can get in winter. In the past, I've cut my strawberries in half or even smaller pieces before freezing. Save yourself a step. Cutting them up is unnecessary, just remove the hull (the green top). Keep reading for my trick to…

developed several freeze wart substances that are safe to use. Freezing warts off has become a favored treatment for quickly removing warts. What Is the Best Way to Freeze Wart Off Safely? Is There a Way I Can Freeze Off a Wart at Home? Warts will generally go away without treatment, but that can take a long time. If your warts are unsightly or painful, you probably want them to vanish quickly. For many individuals, freezing a wart is a common way to quickly rid themselves of the ugly…
