Answer: Here is my attempt. Not sure if it's good enough.
Boyle’s law lab report
This experiment starts asking the question, “What is the effect of pressure on a volume of gas?”. My hypothesis is that adding pressure to gas will not change the amount of gas, but pressure and volume are inversely proportional. As weight was added to the top of a syringe, the volume of the air trapped in the syringe decreased. The weight and the surface area of the plunger were used to calculate pressure. As more weight was added, the pressure increased. The volume decreased in response. I used a syringe, a book, and some weights. The syringe has markings that are easily readable, it will not leak gas, and the volume can change. The book is used to increase pressure on gas. It can also support additional weight. I removed the cap from the syringe, and then removed the plunger. I added some silicone drops to prevent friction. I reinserted the plunger and replaced the cap. I then suspended the syringe from a ring stand using a burette clamp. I then weighed the book. It weighed 0.498kg. I put the book on top of the syringe and calculated the pressure using p=1.03+Mass on syringe/area of top of syringe. I did the same thing after adding 1kg, 2kg, 3kg, and 4kg of weight to the book. (See chart below)
Mass Pressure (kg/cm^2) Volume (mL) Product
0.498 1.08 47.5 51.3
4.498 1.18 43.5 51.3
2.498 1.27 40.5 51.4
3.498 1.37 37.5 51.4
4.498 1.47 35 51.5
To answer this question, you used weight to change the pressure of the gas and measured the resulting changes to the gas’s volume. The amount of gas (in terms of moles, mass, and molecules) was constant. Based on Boyle’s law, pressure and volume were expected to be inversely proportional. If pressure on gas is increased, then it’s volume will decrease because the gas molecules will be pushed closer together.
