Investigate the cooling rate of salol in relation to the pressure it is under, in an attempt to model similar conditions for a cooling igneous intrusion.

Geology Investigation: cooling of Salol due to pressure Aim To investigate the cooling rate of salol in relation to the pressure it is under, in an attempt to model similar conditions for a cooling igneous intrusion. Method In order to simulate the pressure exerted by the surrounding rock, I intend to look at the cooling salol underneath certain depths of water. The salol under the deeper water will naturally be under the greater pressure, while the salol under the least water will similarly be under the least. As such, I will first put 0.1ml salol onto a slide, cover it will a slide cover slip, and wrap it in cling film to stop water getting in. I will then put it under the water at different depths, and leave the salol to cool. After a certain period of time, when the crystals have formed, I will remove the slide from the water, remove the ling film, and measure the size of the crystals of salol. As a secondary experiment, I shall also look at how the size of the igneous body effects the rate at which it cools and thus the size of the crystals. ...read more.


However, due to the fact that I still have belief in the fact that my prediction was sound, I would offer an alternate explanation for this than that my prediction was incorrect. Before I carried out the experiment, although I was confident that I could use the depth of water to calculate the pressure that the salol was under, I was unaware of the nature and proportion of this relationship. When I calculated this (see Results) I found out that the amounts of water I have used make virtually no effect on the pressure at the bottom of the beaker, certainly not enough for us to reasonably expect it to have any impact on the cooling time and thus the size of crystals. As such, it only remains to be explained why there was such fluctuation in the results despite the clear non-influence of the presiding factor. The only sensible suggestion is that there was another, less controlled factor playing a large part: this will be looked at in more detail in the evaluation. Regarding the expansion experiment, it is clear from the graph alone that there is a definite relationship between the size of the crystals and the size of the salol mass, though, this time, it is completely opposite to the relationship suggested by me in the prediction. ...read more.


I would also need to use a substantially larger mass of salol, because this would be much less susceptible to small-scale fluctuations in factors such as the shape of the mass and the insulation. I add here for lack of a better placement the note that I have changed the range of depths to being 0, 90, 180, 270, and 360 cm^3 in order to present a realistic change in the depths of the water that the salol is under. The previous depths were barely different from each other, and they barely even covered the slide. My second experiment was more successful, the results being fairly conclusive and reliable. The fact that they disagreed with my prediction does not matter, in that they showed a clear relationship between the two factors. As I comment in my conclusion, however, I still believe that were the salol unconstrained or (for the purposes of this experiment, given that we need flat crystals to measure) confined along a plane, the crystal size would be greater in larger bodies, because the crystals have more time to form. This would be a suitable extension to the experiment, although there is already secondary evidence from real life igneous intrusions. This experiment, therefore, I consider a success. ?? ?? ?? ??

    Investigating the rate of cooling water in a beaker.

    That is, the difference between its temperature and the temperature of the surrounding environment. Other than just studying the factual theory behind this investigation, I have also done some preliminary work. My preliminary work was based on "What effect does insulation have on the rate of cooling water".

  2. Factors Affecting Cooling

    By doing this each experiment and each beaker was subjected to a fair and equal test. Secondly I found out that the water loses heat differently from the glass to the air. To counter this I shall be putting a piece of card on top of the beaker to stop air getting into it.

  1. An investigation to investigate the effect of the diameter on the cooling rate of ...

    The water particles at the top of the beaker will radiate the heat energy into the surrounding air. For heat to radiate it does not need to be in contact with matter. Heat can radiate for something to another body through a complete vacuum, this is how the sun heats up the earth.

  2. What factors affect the rate of cooling of an animal?

    This happens mostly in animals with less body coverings. Where the environmental temperature has a bigger difference to that of the animal. During radiation, heat is transferred in waves. Some animals, e.g. the polar bear live in artic conditions and have to adapt to the environment and decrease the amount of heat It loses and conserve heat.

  1. I am going to investigate the rate of cooling in heated water. In my ...

    I predict that larger surface areas cool faster than small surface area because there is bigger top surface area so there are more molecules. They gain more energy to leave the beaker and join the rest of the gases and leave the water cooler because having lost the molecules with

  2. To investigate the effect of insulators on the rate of cooling.

    So, therefore the rate of cooling will be very less. I think this will happen because as the beaker is made of copper, which is a good conductor, the high temperature of the water will reduce rapidly. Diagram: Plan of Experiment Apparatus I will use in this experiment: - Electric

  1. To investigate the effect of insulators on the rate of cooling.

    I think that in the end result the graph will look something like: Prediction: I predict that when I change the amount of layers of bubble-wrap around my beaker, the more layers there are the slower the rate of cooling will be.

  2. The Cooling Rate Of A Fluid

    * Convection. Convection involves the heating of molecules in a fluid so that they rise through similar but cooler molecules, allowing more cool particles to move into the position where they may gain energy and in turn rise. This results in energy spreading across a concentration gradient so that both sides become equal.
