Gas Law Lab

This lab contains two experiments that both test the knowledge of the gas law and how it applies to the state that is necessary to form a cloud and to calculate the rate of effusion of CO2 (carbon dioxide) leaving a balloon. If carbon dioxide is placed into a balloon for a period of time, then the carbon dioxide will effuse out of the balloon at a linear rate, because of the pressure that the gas is placing on the wall of the balloon that will allow it to escape from the balloon's microscopic pores. If a match is placed into a flask with room temperature water and heated water, then the resulting cloud that forms in the heated water will have a higher volume and a higher pressure than the cloud that forms in the room temperature water.

The creation of the cloud is controlled by the pressure, volume, and temperature of the cloud and its surroundings. In order to study the effects of any changes in the pressure, temperature, or volume the Combined Gas Law will be implemented after this part of the experiment has been completed. To complete this portion of the experiment, a sample of water will be placed into a side-arm Erlenmeyer flask with a stopper that has an inserted thermometer. One side of a rubber tube will be put onto the side-arm of the flask and the other side will be attached to the opening of a syringe. This allows the volume to be manipulated and the temperature and pressure to be altered. Then a math will be lit then blown out and dropped into the flask. This will produce ash particles that will serve as the condensation nuclei. The syringe will be used to push pressure into the flask to turn the air from clear to "cloudy." The process of forming the cloud will be done at room temperature and at 30 degrees Celsius and the purpose is to determine the dew point pressure at both
