CHE 108 Charles' Law Worksheet Prof. Deora Charles' Law (Temperature in Kelvin) V V T,- T; Solve the following problems assuming a constant pressure. K =_'C + 273). (Note: For Charle's law, volume can be in any unit but temperature has to be in Kelvin!) 1. A sample of oxygen occupies a volume of 350 mL at 300 K. What volume will it occupy at 360 K? 2 Chlorine gas is at a temperature of 323 K when it occupies a volume of 3.2 L. At what temperature will the volume be 5.8 L? 3. Neon gas was heated from 298 K to 398 K. Its new volume is 175 mL. What was the original volume? 4. Helium has a volume of 36 mL at 400 K. What volume will it have at 600 K? (K = temp. in Kelvin) Boyles' Law: P,V, = P,V, (UNITS OF PRESSURE THAT CAN BE USED: atm, torr or mm of Hg) s. Nitrogen gas at 2 atm occupies a volume of 500 mL. At what pressure will it occupy a volume of 250 mL? 6. Argon gas occupies a volume of 5.4L at 760 torr. What volume will it occupy at 550 torr? 7. A sample of helium has a volume of 280 mL at 650 torr. At what pressure will its volume equal 500 mL
