Gas Laws

• Freezing is 0°C and 273 K
• the behavior of gases is related by temperature, pressure & volume.
• T° = the amount of heat in something
• P = the amount of force on an area at sea level
• Boyle's law states that if the pressure increases, then the volume decreases.
• V = the amount of space occupied by something
• Charles's law states that as the temp increases, so does the volume.
• Liter (L)
• Milliliter (mL)
• Cubic centimeter (cm³, dm³, m³, etc.[a cubic length])
• 1 atmosphere = 1 atm
• 760 millimeters of Mercury = 760 mm Hg
• 760 mm Hg = 760 Torr
• 101300 Pascals = 101.3 kPa
• 14.7 pounds per square inch = 14.7 psi
• 29.92 inches of Hg
• Boiling is 100°C and 373 K
• Celsius (°C)
• Kelvin (K)
• We must always use Kelvin when doing math.
• To convert Celsius (°C) to Kelvin add 273.
• To convert Kelvin to Celsius (°C) subtract 273.
• STP = standard temperature and pressure at sea level
• Standard temperature and pressure (STP) is a standardized set of conditions used to measure the temperature and pressure of a sample
• gases, when placed in air or hydrogen will float, sink or do neither based on a hydrogen or air standard
• > 1 = sink
• 1 = neither (suspended)
• < 1 = float
• hydrogen standard (molar mass of gas) x/2
• air standard (molar mass of gas) x/29
• P1V1 = P2V2
• Pressure and Volume are inversely proportional
• decrease pressure = increase volume
• increase pressure = decrease volume
