Boyle’s Law 5-1: Boyle’s Law: Pressure and Volume Robert Boyle, a philosopher and theologian, studied the properties of gases in the 17thcentury. He noticed that gases behave similarly to springs; when compressed or expanded, they tend to ‘spring’ back to their original volume. He published his findings in 1662 in a monograph entitled The Spring of the Air and Its Effects.You will make observations similar to those of Robert Boyle and learn about the relationship between the pressure and volume of an ideal gas. 1.Start Virtual ChemLab, select Gas Properties,and then select Boyle’s Law: Pressure and Volumefrom the listof assignments. The lab will open in the Gases laboratory. 2.Note that the balloon in the chamber is filled with 0.300 moles of an ideal gas (MW = 4 g/mol) at a temperature of 298 K, a pressure of 1.00 atm, and a volume of 7.336 L. To the left of the Pressure LCD controller is a lever that will decrease and increase the pressure as it is moved up or down; the digit changes
