    The freezing point of p-xylene was calculated as 13.29C after averaging the data that appeared on Graph 1 once the temperature leveled off. With this value, the Tf for each trial was able to be calculated through Equation 1, which led to Kf being calculated in Equation 2. Both equations were able to be used given that the measurements were in terms of molality, which is not temperature dependent. After completing calculations, the average Kf of the three trials of the p-xylene and toluene solution

    Mr. Blank 4/9/02 Effects of Salts on the Freezing Point of Water In this experiment, you will study the effect that several solutes have on the Freezing Point of water. When a solute is dissolved in a liquid, the temperature at which that liquid freezes decreases, because the molecules of the solute become attached to the water molecules, making it more difficult for the water to form its crystaline shape and form into ice. This process is called Freezing Point Depression. In this experiment, you

    Genetic Engineering and Cryonic Freezing: A Modern Frankenstein? In Mary Shelley's Frankenstein, a new being was artificially created using the parts of others. That topic thus examines the ethics of "playing God" and, though written in 1818, it is still a relevant issue today. Genetic engineering and cryogenic freezing are two current technologies related to the theme in the novel of science transcending the limits of what humans can and should do. Genetic engineering is widely used

    Freezing point depression: First, the freezing point depression of magnesium chloride was found. To begin, an ice bath was created in a 600 mL beaker filled with ice provided in the laboratory and rock salt. Next, Four different solutions with concentrations of 0.0 g (control), 0.2 g, 0.4 g, and 0.6g of magnesium chloride and 15 mL of deionized water were created. Each solution was made in a 100 mL beaker. The solutions containing magnesium chloride were stirred with a glass rod until the salt was

    Katrina Epps Lab Partner: Jennifer Carter Tim Little CHE113-011 17 February 2014 Freezing Point of Sugar and Salt Introduction The purpose of this lab was to determine the molality of sugar and salt substance through calculating the freezing point depression (freezing point depression is the effect of lowering the freezing point of a substance due to an increased amount of solute added to the solvent in that the solute decreases the amount of vapor pressure) when the sugar or salt substance is added

    When we had to choose a preservation method, automatically the “freezing” method came to my mind. I personally think that this method is very effective and very practical in proffesional kitchens. Freezing, in food sectors is a method of preserving food by dropping the temperature to prevent microorganism build up. There are numerous of food ingredients that you can freeze, fresh vegetables and fruits, meats and fish, breads and cakes, and clear soups and casseroles. Whereas there are many foods

    Purpose: The purpose of this experiment was to determine the temperatures of the freezing and the melting points of water. Background: In order to understand this experiment, some background information was needed. For example, a person must understand what a melting point and what a freezing point is. A freezing point is defined as a temperature at which a liquid changes into a solid. A melting is the opposite of the freezing point. It is defined as a temperature at which a solid, turns into a liquid

    pushes the surface upwards; there are three criterion which need to exist for frost heave to occur, 1. A sufficiently cold climate to allow freezing temperatures to penetrate below the surface 2. A supply of water from below, above or laterally into the freezing zone. 3. A soil material that is frost susceptible and is lying within the freezing zone. The heaving itself is caused by the formation of ice lenses in the soil below, which refers to the growth of ice crystals in the soil

    Option" written by Sally Wadyka, focuses on the new improved technology of Oocyte cryopreservation, or the freezing of eggs. It has become a recent trend for women to wait till later in their lives to start a family. Until recently, there was no procedure available for women to store their eggs to be used at a later date. Because of this trend and the new advances in the field of egg freezing, in this essay I will attempt to provide background information on the technology, advances made to this
