In which medium the speed of sound is greater : in moist air or in dry air ?

Explanation

To determine in which medium the speed of sound is greater, we need to compare moist air and dry air. Here’s a step-by-step solution:

### Step 1: Understand the formula for the speed of sound
The speed of sound in a gas can be expressed using the formula:
\[ v = \sqrt{\frac{p}{\rho}} \]
where:
- \( v \) is the speed of sound,
- \( p \) is the pressure of the medium,
