"In this law the volume stays constant. Temperature and pressure are directly related; both increasing or both decreasing." (http://katelynreding.blogspot.com/p/gas-laws.html) Real World Example: When you open a container of hot food and you feel the flow of air it is becuase pressure is being released inside. When the dish has a lid on it is building up pressure inside. The food being hot is an increase in temperature and the volume is staying constant.
"In this law the pressure stays constant, or the same. Temperature and Volume are directly related; meaning that the temperature and volume either both go up or both go down." (http://katelynreding.blogspot.com/p/gas-laws.html) Real World Example: If you leave a basketball out in the cold it loses air inside, or volume. This shows that with constant pressure the temperature dropping causes the volume to decrease. Likewise if the temperature increases the volume would as well. So if you bring the basketball back out in the summer or when it's warm out it would start to gain volume back.
"Robert Boyle studied the relationship between the pressure p and the volume V of a confined gas held at a constant temperature. Boyle observed that the product of the pressure and volume are observed to be nearly constant. The product of pressure and volume is exactly a constant for an ideal gas." (https://www.grc.nasa.gov/www/k-12/airplane/boyle.html) Real World Example: A spray can like of spray paint or air freshener is an example of this law. Inside of the can there is an intense build up of pressure but a minimal amount of volume in the can. When you press down on the top it opens a hole in which some of the pressure is let out which creates the paint or smell. With the temperature staying the same throughout, the intense pressure is varied indirectly with the minimal amount of volume allowed in the spray can.
