Ice Lab and its Phase Changes

Extracts from this document...


Lab 1: Ice Lab and its phase change Introduction: Everything is made up of matter. It has shape, volume and mass. All one hundred and nine elements have three states and provide the world with daily activities. An element at a solid state has particles that are very close together and vibrate. A solid state has a set shape, mass and volume and this gives it a tough shape. The second state of an element is a liquid and it also has a set volume and mass. In this state the particles vibrate and rotate in a limited space. However, like the solid they do not have a rigid shape, liquids are shaped liked the object in which they are poured. The last state of the elements is a gas. Particles of gas are very free and can vibrate, rotate, move rapidly, and the shape of gas is not known. These three states are very amusing when one experiments and looks at the changes from one phase to another. In addition, when one state changes from solid to liquid, the particles move more rapidly and the energy is more increased. ...read more.


III. Use the electronic scale and weigh the 250ml graduated cylinder and after obtaining the weight add ice. (About 102.6g of ice) IV. In the graduated cylinder put in the thermometer and record the temperature of the ice after every 10 seconds. V. The room temperature should be around (18.2�C). VI. Place the thermometer in the beaker filled with water after getting rid of the ice. VII. Now record the temperature of the water every 10 seconds. This should be done for about 17 minutes. VIII. Dispose of water and return lab equipment in the proper place. Variables: Time in an independent variable. Temperature is dependent variable. Observations: Tables: Erroneous Procedure with 3 ice cubes 1. Mass- 101.7grams, Solid to Liquid. With Ice.

The temperature for water to melt is less than zero degrees Celsius. At this stage the one can see that it is evident that the graph would show a less curve because no plateau will be present. This can be related to the increase in kinetic energy does not effect the phase change but converts to the potential energy. This is simply noted that kinetic energy does not play a big role when the phase changes. So this answers our question that, "Why does the temperature remain the same while the phase changes," well this is due to kinetic energy helps increase the potential energy and this keeps the temperature constant. In conclusion, some experimental errors were made but in the end I tried my utterly best to prove my point. Conclusion: Analyzing the data and the graphs it is proved that "Yes," when the water begins to change from solid to liquid, the temperature does remain constant while the phase changes. This also represents that during the plateau, the solid and liquid phases are all present during the similar period of time and this is all due to kinetic energy converting into potential energy and making this happen. Lastly, this lab clearly shows and proves that the temperature remains the same while the phases change and become the final product. ...read more.

    as least as possible to avoid the equilibrium position shifting to right (? by Le Chatelier's principle, the increase in [H2O(l)] promote the equilibrium shifts rightward). More CH3COOH(l) is formed and hence alters the Kc. The reagent bottles containing ethyl ethanoate should be sealed besides stopped to avoid vapourization of CH3COOCH2CH3(l)

    Thus beryllium, combining weight 4.6, was given the valency 3 because it was chemically similar to aluminium. This gave an atomic weight of 13.8, placing it between carbon and nitrogen where there was no space. Mendeleev said the valency was 2; the problem was solved - it fitted into the space between lithium and boron.

  2. Investigating the enthalpy change of different fuels when combusted.

    In this experiment there is only 1 dependant variable for each alcohol and that is the change in mass of the spirit burner + alcohol + lid. This will allow us to calculate the enthalpy change and therefore how much energy is required to heat up water through 20�C.
