Coursework: The diffusion of Ammonia Gas
Introduction
Diffusion is the way gases spread out to occupy all the space available to them, this is because they move from a concentrated area of the gas to a less concentrated area of the gas.
As I have done this experiment in a previous lesson I will use my results from the previous lesson as a source of information, comparing those results with the results I get this time.
Factors that may affect the diffusion of ammonia gas
The factors that may affect the outcome of the diffusion are the temperature as it may produced more gas and the heat energy will increase the speed at which the gas particles are moving. The diameter of the tube because the gas has more space in the tube, the wider it gets and less to fill if it is smaller. The concentration of the solution is also a factor as a higher concentration may give off more gas than a solution with a lower concentration. Also the distance between the litmus paper is a factor because if it is a small distance then it will take less time for the gas to reach the next litmus, but is they are further apart then it will take longer. Finally, the angle of the tube is also a factor because depending on the angle it may take a longer or shorter time to change the colour of the litmus paper.
