Root Mean Square Speed
A measure of the average velocity of gas particles, calculated using the formula involving temperature, molar mass, and the ideal gas constant.
Velocity
The speed of gas molecules in a specific direction, crucial for understanding gas behavior.
Gas Molecules
Particles that make up gases, whose motion is described by kinetic molecular theory.
Formula
A mathematical expression used to calculate the root mean square speed of gas molecules.
Square Root
A mathematical operation used in the RMS speed formula to determine the velocity of gas molecules.
Molar Mass
The mass of a given substance divided by the amount of substance, expressed in kg/mol for RMS speed calculations.
Kilograms per Mole
The unit of molar mass used in the RMS speed formula, ensuring consistency with the ideal gas constant.
Ideal Gas Constant
A constant used in the RMS speed formula, valued at 8.314 J/(mol·K) for speed calculations.
Temperature
A measure of thermal energy, expressed in Kelvin, affecting the speed of gas molecules.
Kelvin
The unit of absolute temperature used in the RMS speed formula, ensuring accurate calculations.
Kinetic Molecular Theory
A theory that relates the macroscopic properties of gases to the microscopic motion of molecules.
