  • Standard Temperature
    A reference point set at 0 degrees Celsius or 273.15 Kelvin, used for consistency in gas calculations.
  • Standard Pressure
    A reference value of 1 atmosphere, commonly used in gas law calculations for uniformity.
  • STP
    A set of conditions, specifically 273.15 Kelvin and 1 atmosphere, used as a baseline for gas measurements.
  • Ideal Gas
    A theoretical substance whose particles occupy negligible space and experience no intermolecular forces.
  • Standard Molar Volume
    The space occupied by 1 mole of an ideal gas at STP, numerically equal to 22.4 liters.
  • Mole
    A counting unit representing Avogadro's number of particles, often used to relate mass and volume in chemistry.
  • Gas Constant
    A proportionality factor, symbolized as R, used in equations relating pressure, volume, temperature, and moles.
  • Atmosphere
    A unit of pressure defined as the average pressure at sea level, equivalent to 101.325 kPa.
  • Kelvin
    An absolute temperature scale starting at absolute zero, commonly used in scientific temperature measurements.
  • Conversion Factor
    A numerical ratio, such as 1 mole equals 22.4 liters at STP, used to switch between units in calculations.
  • Volume
    The amount of three-dimensional space occupied by a substance, often measured in liters for gases.
  • Liter
    A metric unit of volume commonly used to express the amount of space a gas occupies.
