Name_____________________________ Period_____Date_____/_____/______ Boyle’s, Charles’s & Gay-Lussac’s laws Worksheet You need to show work to get credit. To solve the following, you will need to first find out what information is being given and then what information is being asked for. Once you know what kinds of variables you need, you can choose a gas law. Reminder, calculations MUST be done in degrees Kelvin! oK = oC + 273.15 Units Pressure – Pa (or kPa), torr, atm, mm Hg Temperature – oC (Convert to Kelvin!), oK Volume – L (or mL) 1. A balloon has a volume of 253.2 mL at 356oK. The volume of the balloon is decreased to 165.4 mL. What is the new temperature? 2. If I have 5.6 L of gas in a piston at a pressure of 1.5 atm and compress the gas until its volume is 4.8 L, what will the new pressure inside the piston be? 3. Determine the pressure change when a constant volume of gas at 1.00 atm is heated from 20.0˚C to 30.0˚C. Name_____________________________ Period_____Date_____/_____/______ 4. A sample of oxygen gas occupies a volume of 365.2 mL. When the volume is increased to 478.2 mL, the new pressure is 241.3 torr. What was the original pressure? 5. If 72.3 L of an ideal gas is cooled from 36oC to –156oC, what will the volume of the gas become? 6.
