Questions & Step-by-Step Solutions
For a monoatomic ideal gas, the RMS speed is given by which of the following expressions?
Step 1: Understand what RMS speed means. RMS stands for Root Mean Square, which is a way to calculate the average speed of gas particles.
Step 2: Know that for a monoatomic ideal gas, the RMS speed can be calculated using the formula: v_rms = sqrt(3kT/m), where k is the Boltzmann constant, T is the temperature in Kelvin, and m is the mass of a gas particle.
Step 3: Another formula for RMS speed is v_rms = sqrt(3RT/M), where R is the universal gas constant, T is the temperature in Kelvin, and M is the molar mass of the gas.
Step 4: Recognize that both formulas are valid and can be used to find the RMS speed of a monoatomic ideal gas depending on the information available.
RMS Speed of Gases – The root mean square (RMS) speed of a gas is a measure of the average speed of particles in a gas, calculated using the formula derived from kinetic theory.
Monoatomic Ideal Gas – A monoatomic ideal gas consists of single atoms and follows the ideal gas law, where interactions between particles are negligible.
