Lab Report: Boyle’s Law INTRODUCTION Purpose: Explore the relationship between pressure and volume of a gas, as described by Boyle’s Law. Question: What is the effect of pressure on the volume ... of a gas? Hypothesis: If the pressure on a gas is increased, then its volume will decrease because the gas molecules will be pushed closer together. Furthermore, the relationship between pressure, P, and volume V, should be an inverse proportion, in which PV is constant and p=kV for some constant, k. Variables: Independent variables: pressure Dependent variables: volume Constant Variables: temperature and number of moles MATERIALS AND PROCEUDRE: Materials -60 ML syringe with cap -Ring stand -Burette clamp -Balance -Silicone lubricant -Ruler - Book -Four 1 kg weights (2 kg weight can be substituted) Procedure: 1. Gather materials. 2. Measure the Area of the Top of the Syringe a. The top of the syringes plunger is a circle. You need to compute its area for use in later computations of pressure values. Start by using a ruler to measure the diameter. Estimate the final significant digit. b. Divide by two to find the radius. Maintain significant figures. c. Substitute the radius into the formula A=π r 2 to find the area of the top of the syringe. Maintain significant figures. [Show More]
