Q. Consider the following statements:
  1. The speed of sound increases with an increase in the density of the medium.
  2. The speed of sound increases with an increase in the temperature of the medium.
Which of the above statements is / are correct?

Answer: Only 2
Notes: The speed of sound in a medium depends on both its density and elasticity. While greater elasticity increases speed, higher density actually decreases it. However, increasing temperature generally reduces density and increases molecular motion, leading to a higher speed of sound. Thus, only statement 2 is correct.
