The speed of sound in a gas depends on its temperature, molecular weight and γ=Cp/Cv, ratio of heat capacity at a constant pressure to heat capacity at constant volume. The γ value for air, oxygen, nitrogen, argon and carbon dioxide was determined by measuring the velocity of the sound through the gases at room temperature. The sound velocity is measured with a microphone using Calculator-Based Laboratory (CBL) Technology.

Abstract
The speed of sound in a gas depends on its temperature, molecular weight and γ=Cp/Cv, ratio of heat capacity at a constant pressure to heat capacity at constant volume. The γ value for air, oxygen, nitrogen, argon and carbon dioxide was determined by measuring the velocity of the sound through the gases at room temperature. The sound velocity is measured with a microphone using Calculator-Based Laboratory (CBL) Technology.File in questo prodotto:
