  • Ideal Gas Law
    A mathematical relationship connecting pressure, volume, temperature, and moles of a gas using the equation PV = nRT.
  • Boyle's Law
    A principle stating that pressure and volume of a gas are inversely proportional when temperature and moles are constant.
  • Gay-Lussac's Law
    A rule describing flexibly that pressure and temperature of a gas are directly proportional at constant volume and moles.
  • Avogadro's Law
    A statement that volume and moles of a gas are directly proportional when pressure and temperature are constant.
  • Charles's Law
    A law indicating that volume and temperature of a gas are directly proportional at constant pressure and moles.
  • Pressure
    The force exerted by gas particles per unit area on the walls of a container, often measured in atmospheres or pascals.
  • Volume
    The amount of three-dimensional space occupied by a gas, typically measured in liters or milliliters.
  • Temperature
    A measure of the average kinetic energy of gas particles, required in Kelvin for gas law calculations.
  • Moles
    A unit representing the amount of substance, specifically the number of particles present in a gas sample.
  • Kelvin
    The SI unit for temperature, used in gas law equations to ensure direct proportionality relationships.
  • Direct Proportionality
    A relationship where two variables increase or decrease together, shown as a straight line on a graph.
  • Inverse Proportionality
    A relationship where one variable increases as the other decreases, depicted as a downward curve on a graph.
  • Movable Piston
    A device in a container allowing volume changes, used to illustrate gas law relationships in visual examples.
  • Adjusted Formula
    A rearranged equation derived from the ideal gas law, tailored to specific variable relationships in each gas law.
