1. Boyles Law Experiment Starter If a cylinder with a piston is full air, how are the volume of the air and the air pressure related? In other words, as the volume is increased of decreased, how will the air pressure change? If a cylinder with a piston is full air, how are the volume of the air and the air pressure related? In other words, as the volume is increased of decreased, how will the air pressure change?

2. Boyles Law 1. Research Boyles Law and write an explanation of the law. Include an equation for law. 2. Design an experiment to analyze Boyles Law by taking volume and pressure measurements for air as the gas. Your volume range should be from 20ml to 10ml in increments of 1ml. 3. Plot your data. Make sure you are clear about which variable is independent and which is dependent. Remember to plot the independent variable on the horizontal axis. 4.Fit your data with a smooth curve and decide if it supports Boyles Law. Explain your reasoning carefully in your summary. Write the equation for your curve on the graph.

3. Questions 1.How does Boyles Law relate to the ideal gas law? 2.If the volume of the syringe is reduced to ½ of the original, what happens to the pressure? 3. Is the air in the room an ideal gas? Explain.

4. Exit A cylinder with a volume of 1.5 liters has a gas in it at a pressure of 5.00 Pascals. If the cylinders volume is changed to 2.00 liters, what is the new pressure?
