1/12
  • Partial Pressure
    Pressure contributed by a single gas in a mixture, calculated independently as if it occupied the container alone.
  • Total Pressure
    Sum of all individual gas pressures present in a container of unreacting gases.
  • Dalton's Law
    Principle stating that total pressure equals the sum of all partial pressures in a gas mixture.
  • Gas Mixture
    Combination of two or more unreacting gases sharing the same container.
  • Ideal Gas Law
    Equation relating pressure, volume, temperature, and moles for a gas assuming ideal behavior.
  • Mole
    Unit representing the amount of substance, used to quantify gas particles in calculations.
  • Gas Constant
    Proportionality factor (R) used in the ideal gas law to relate energy, temperature, and amount.
  • Temperature
    Measure of average kinetic energy of gas particles, influencing pressure in a container.
  • Volume
    Space occupied by a gas, affecting its pressure when other variables are held constant.
  • Percent Composition
    Percentage representing how much of a specific gas is present in a mixture.
  • Fractional Composition
    Proportion of a gas in a mixture, found by dividing percent composition by 100%.
  • Unreacting Gases
    Gases that do not chemically interact with each other within a container.
