Investigating How the Volume of Water Affects the Time It Takes to Boil

The Plan

--------

· Q. What am I trying to find out?

· A. How the volume of water affects the time that it takes to boil.

· Q. What do I think will happen?

· A. The larger the volume the longer the time to boil.

· Q. Why do I think it will happen using scientific ideas?

· A. The larger the volume, the more atoms you need to heat.

· Q. What will I measure?

· A. Time versus volume.

· Q. What will I alter between observations?

· A. The volume of water.

· Q. What will I do to ensure a fair test?

· A. Keep everything the same except the input variable: volume.

· Q. How will I decide on the values of the variables that I will be

using?

· A. Values will be chosen to enable the experiment to be carried out

in a reasonable time, and to give a good range for trend analysis.

· Q. How many measurements will I take and how will they be spaced

out?

· A. 50ml to 200ml in intervals of 50ml, i.e. four different

measurements.

· Q. What equipment will I need and how will I use it?

· A. Timer; Beaker; Tripod; Bunsen Burner; Gauze; Heat Proof Mat

(HPM); Goggles:

Goggles,Timer,Gauze,Beaker,Bunsen Burner

Tripod

HPM

· Q. How will I take any safety situations into account?

· A. Wear your goggles at all working times to protect your eyes from

boiling water; HPM to prevent ignition and overheating of the desktop.

· Q. How will I ensure that my experiment is reliable?

· A. I will repeat the investigation at least once.

· Q. How will I record the results?

· A. I will record times in whole seconds.

    It was learned that changing the volume of the same substance will never change the boiling point of the substance. However having two different substances with the same volume will result in two different boiling points. The purpose of this lab was to determine if changing the volume of a substance will change the boiling point. This is useful to know in real life because if someone wanted to boil water to make pasta and did not know how much water to

    At a constant temperature, a pure liquid has a vapor pressure that describes the pressure of escaped gaseous molecules that exist in equilibrium at the liquid’s surface. Adding energy to a pure liquid gives more molecules the kinetic energy to break the intermolecular forces maintaining the liquid and raises the overall temperature of the liquid. Eventually, adding energy boosts the liquid’s vapor pressure until it equals the surrounding atmospheric pressure. When this occurs, the pure liquid boils at a temperature called the boiling point.

    With knowledge of a pool boiling curve, it is possible to predict the amount of heat transfer induced by the boiling of a fluid. The level of heat transfer that can be obtained for engineering applications is highly dependent on the difference in temperature between the heating surface and the surrounding fluid. The shape of this curve is dependent on the shape of heating surface as well as the material properties of the heated surface and fluid. Both empirical constants and dimensionless numbers are used to form a boiling curve. Optimal operation conditions for an application can be predicted with the understanding of how different factors can shape the boiling curve [1].

    Objects that are not the same size but have the same surface area to volume ratios loose heat at the same rate. So a flask, with a volume of 200cm3 with a surface area of 160cm2 and a surface area to volume ratio of 1.25:1, will loose heat at the same rate as a similar flask of volume 625 and a surface area of 500 which also has a surface area to volume ratio of 1.25:1. However, generally when you increase the size of an object the surface area to volume ratio decreases so in this example it is very likely that the two flasks in question are different shapes.

    From the graph 2, it is seen clearly that the relationship between purity and boil-up rate is inversely proportional to each other. In order to achieve a good separation and high purity between the liquid and the vapour must be brought to an intimate contact by counter-current flow. Increasing the vapour flow actually means decreasing the interaction time between the down flowing liquid and up flowing vapour inside the column. Hence, if ...

    First of all, the purpose of this lab was to determine the water’s vapor pressure at different temperatures as well as to measure the molar heat of vaporization of water using the Clausias Clapeyron equation. The first concept out of many represented in this lab is the ideal gas law. The ideal gas law is used to get the number of moles of air trapped in the 10 mL graduated cylinder. Once we cooled the system so that water vapor is extremely minute, and then we determined the number of moles of air using the ideal gas law. The number of moles of air equals to the pressure (in atm) times volume divided by constant times temperature. One would assume that when the water is heated to 80 degrees, the number of air molecules in the air bubble would decrease, but it actually stays constant. This is due to the fact that there is no air coming in or out of the cylinder. As the temperature gets closer to 80 degrees, the number of air molecules stays the same but the water vapor increases. And the bubble expands to keep the pressure at the same level. The ideal gas law was also used when the partial pressure of air in the gas mixture is calculated. This is gotten from number of moles multiplied by the constant and the constant and the whole thing divided by the volume.

    6. When water is distilled, it does not vaporize all at once when the boiling point is reached. When some water molecules evaporate, the kinetic energy of the remaining liquid goes down and the temperature drops slightly. As a result, the rest of the water needs to be heated again before more molecules of water evaporate. A constant source of heat is needed.
