The Freezing Point Of P Xylene

- 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 was computed as as 4.56(C/m) as shown in Table 1, however, the theoretical value was slightly lower than calculated, 4.3(C/m)....   [tags: Solvent, Solubility, Melting point]

Investigating The Molar Mass Of A Substance

- The overall purpose of this lab was to determine the molar mass of an unknown. There are various methods for determining the molar mass of a substance such as freezing point depression, boiling point elevation, osmotic pressure, and vapor pressure lowering. These methods are often referred to as colligative properties, which can only be applied to solutions.

The Mechanisms and Effects of Frost Heave

- The Mechanisms and Effects of Frost Heave ABSTRACT Frost heave is the increase in volume experienced by soils when they freeze. Water moves to the upper horizons from below; when it freezes it forms segregated ice lenses which push apart the soil around them as they grow, causing the observed volume increase. Frost heave has a number of effects upon the soil and upon structures supported by the soil which make it an important process to understand.

- Solar nebula is a rotating flattened disk of gas and dust in which the outer part of the disk became planets while the center bulge part became the sun. Its inner part is hot, which is heated by a young sun and due to the impact of the gas falling on the disk during its collapse. However, the outer part is cold and far below the freezing point of water.
