Question

For an ideal gas, the speed of sound is given by the formula v = √(γRT/M). What does the term γ represent in this formula, as defined in the document?
Options
A The specific heat capacity at constant volume.
B The specific heat capacity at constant pressure.
C The ratio of specific heats (<i>cₚ/cᵥ</i>).
Correct Answer
D The molar mass of the gas.
Correct Answer

Option C is the correct answer.

Detailed Explanation

On page 14, in the section discussing the speed of sound in a gaseous medium, the document states: 'For a gaseous medium, we can express the Bulk modulus in terms of the undisturbed gas pressure p₀ as B = γp₀, where γ is the ratio of specific heats (cₚ/cᵥ) for the gas.' This directly defines γ.

Hint

Refer to the 'Speed of Sound in Ideal Gas' section on page 14 to find the definition of γ.
