ABSTRACT

Gases behave in a similar way over a wide variety of conditions because to a good approximationthey all have molecules which are widely spaced, and nowadays the equation of state for an ideal gas isderived from kinetic theory. The combined gas law or general gas equation is formed by the combination of the three laws, and shows the relationship between the pressure, volume, and temperature for a fixed mass of gas. The Gas Laws that have been subject to testing were Combined Gas Law and Graham’s Law.

INTRODUCTION

The combined gas laws a gas law which combines Charles's law, Boyle's law, and Gay-Lussac's law. These laws each relate one thermodynamic variable to another mathematically whileholding everything else constant. Charles's law states that volume and temperature are directlyproportional to each other as long as pressure is held constant. Boyle's law asserts that pressure andvolume are inversely proportional to each other at fixed temperature. Finally, Gay-Lussac's law introducesa direct proportionality between temperature and pressure as long as it is at a constant volume.

EXPERIMENTAL PROCEDURE

A. Effect of temperature on solubility of a solid in water.
a. Put 1g of KCl (Potassium Chloride) in 10 ml water with an ignition tube at 10°C, then shake and observe the solubility of KCl.
b. Heat the solution to 40°C and not higher, then stir and observe its solubility.
c. Add another gram of KCl in the mixture, then stir and observe the solubility. Heat the mixture in an 80°C water bath then shake and, once more, observe the solubility of the KCl.
d. Repeat the procedure with NaCl (Sodium Chloride).

B. Effect of the polarity of the solute and solvent
Determine the solubility of 1 g (solid) or 1 mL (liquid) of the solutes in 1 mL water, 1 mL

    The respective volumes of each solution were measured out in graduated cylinders and combined in a large beaker (to increase surface area for evaporation). With added heat to speed up the process, the water dissolved off leaving only the white powdery solid KCl. 0.937 g of substance was the final mass which since the theoretical yield was 1 g gave a 93.7% yield. Some KCl was likely evaporated with the water and some was likely lost in transferring from the beaker to the watch glass, so a 93.7% yield is adequate.…

    The purpose of this lab was to determine the effect of temperature on the volume of gas when the pressure is consistent and to verify Charles’ Law. The data from the experiment reveals that as temperature increases, so does volume. This also indicates that as temperature decreases, the volume decreases as well.…

    Charles’s Law (also known as the law of volumes) is an experimental gas law which describes how gases tend to expand when heated. At constant pressure, the volume of a given mass of an ideal gas increases or decreases by the same factor as its temperature on the absolute temperature scale. It can be written as V∞T where V is the volume or the gas and T is the absolute temperature.…
