Consider the following statements:

  1. Speed of sound increases with increase in density of the medium
  2. Speed of sound increases with increase in temperature of the medium

   Which of the above statements is/are correct?

Answer: [B] 2 Only

When the elasticity of the medium increases the density decreases and it increases the sound speed. Higher temperatures lower the density of a medium, which puts less resistance on the sound waves.
