Unit 12- Gas Laws
Learning Targets
collect, analyze, and interpret data relating to changes in gas pressure, volume, and/or temperature
explain the cause of gas pressure as the collisions of particles with the walls of a container
convert temperature between degrees Celsius (oC) and kelvins (K)
convert gas pressures between units of atm, kPa, and mmHg
describe how changes in volume, temperature, and number of particles affect gas pressure
apply gas laws to predict gas behavior based on changes in:
--- pressure , volume , temperature , number of particles
define standard temperature and pressure (STP) as 273 K and 1 atm
apply the combined gas law to calculate changes in pressure, volume, and temperature
apply the ideal gas law (PV = nRT) to calculate the pressure, volume, moles, temperature, or molar mass of a
gas (Honors)
recall or calculate the molar volume of a gas at STP as 22.4 L/mol (Honors)
perform stoichiometric calculations for gas reactions using volume ratios, ideal gas law, or molar volume at STP (Honors)
Vocabulary
Gas Pressure- A force caused by collisions between gas particles and the walls of a container.
Gas Pressure is measured in several different units… You should be able to convert from one unit of pressure to any other.
1 atmosphere = 760 mmHg = 760 torr = 101.3 KPa
STP- Standard Pressure and Temperature
Standard temperature = 0oC or 273 K; Standard Pressure = 1 atm or 760 mm Hg
NOTE- When using the formulas, remember that all TEMPERATURES must be in KELVIN.
o
C + 273 = K
Boyle’s Law
As the pressure on a gas increases, its volume will decrease (T = constant)
Gas Pressure and Volume are INVERSELY proportional.
Charles’ Law
As the temperature of a gas increases, its volume will also increase (P= constant)
Temperature and Volume are DIRECTLY proportional.
Combined Gas Law
Ideal Gas Law
Gas Constant = R= 0.0821 L atm/mole K
Molar Gas Volume
One mole of any gas, if under standard conditions (STP), will occupy 22.4 L of space.
1 mole = 22.4 L (at STP)
Gas Stoichiometry
All stoichiometry problems will include a mole ratio (mole- mole) conversion step.
