Speed of Sound in Ideal Gases: Variation & Derivation

AI Thread Summary
The speed of sound in an ideal gas varies with temperature, being directly proportional to the square root of the absolute temperature. The relationship is expressed by the formula c = √(kRT), where c represents the speed of sound, k is the ratio of specific heats, R is the ideal gas constant, and T is the temperature. Contrary to initial assumptions, the speed of sound is not directly proportional to the medium's density. Understanding this relationship is crucial for applications in aerodynamics and thermodynamics. The discussion emphasizes the importance of temperature in determining sound speed in gases.

how does the speed of sound vary with temperature in an ideal gas? how do we derive this relation?
 
Physics news on Phys.org
Isn't the speed of sound directly proportionate to the medium's density?
 
The speed of sound is proportional to the square root of the absolute temperature:

c = \sqrt{k R T}

where:
c = speed of sound
k = ratio of specific heats (1.4 for air)
R = Ideal gas constant
T = Temperature
 
thanks guys...
 
Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...
I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
