The universal gas constant (R) is a constant value used in the ideal gas law equation to relate the pressure, volume, temperature, and number of moles of a gas. It has the same value for all gases under ideal conditions.
Think of R as a key that unlocks the relationship between different properties of gases. Just like how one key can open multiple doors, R allows us to unlock various gas-related calculations by connecting pressure, volume, temperature, and moles.
Ideal Gas Law: An equation that describes the behavior of an ideal gas by relating its pressure (P), volume (V), temperature (T), and number of moles (n).
Boyle's Law: A gas law that states that at constant temperature, the volume of a given amount of gas is inversely proportional to its pressure.
Charles's Law: A gas law that states that at constant pressure, the volume of a given amount of gas is directly proportional to its absolute temperature.
