Question
For an ideal gas, how is the speed of sound primarily dependent on temperature (T)?
Correct Answer
Option C is the correct answer.
Detailed Explanation
On page 14, in the section 'In an ideal gas,' the formula for the speed of sound is given as 'v = √(γRT/M)'. This clearly shows that v is directly proportional to the square root of temperature (√T). The text further simplifies this to 'v = 20.04√T' for air.
Hint
Locate the formula for the speed of sound in an ideal gas and observe the relationship with temperature.
