The best graph Rob can use to show his data is a scatter plot. A scatter plot shows a relationship between two sets of data in this case the solids and their respective solubility. A scatter plot is very specific in showing how one variable is affected by another variable.
The true factor in the atmosphere which perfectly explains the student’s observations is: High levels of moisture are contained within an air mass. This goes to say clearly that a very high humidity concentration in the air mass account for the best factor in the atmosphere in the student's observations
<h3>Air mass</h3>
An air mass is a huge body of air in the lower atmosphere that has similar temperature, humidity, and air pressure at given height
<h3>Air mass interaction</h3>
When two different air masses come into contact together, they don't mix. Rather, they push against each other along a line called a front. When a warm air mass meets a cold air mass, the warm air rises since it is lighter. At high altitude it cools, and the water vapor it contains condenses.
<h3>Humidity</h3>
Humidity is the amount of water vapor in the air. Ofcourse, if there is a lot of water vapor in the air, the humidity will be high as well.
