Boyle's Law Apparatus
Ever wondered what happens to air when you squeeze it? That's exactly what Boyle's Law explains! This law states that at constant temperature, the volume of gas varies inversely with pressure. When pressure goes up, volume goes down—and vice versa.
The apparatus uses a simple syringe with volume markings and a cap to create an airtight chamber. By placing weights on the plunger, you apply different forces that compress the air inside. The relationship follows the formula V ∝ 1/P, showing how volume and pressure are related.
To calculate pressure, you'll need to measure the syringe's cross-sectional area using the formula P = F/A. The experiment involves adding various weights (500g to 2500g) to the plunger and recording how the volume changes, then removing weights and observing if the volume returns to its original value.
Try This! After collecting your data, plot pressure vs. volume on a graph. If Boyle's Law holds true, you should see a hyperbolic curve showing the inverse relationship. Does your graph look like this?
