      Question

      What is the speed of sound in air at room temperature

      (20°C)?  
      A 343 m/s Correct Answer Incorrect Answer
      B 300 m/s Correct Answer Incorrect Answer
      C 1000 m/s Correct Answer Incorrect Answer
      D 1500 m/s Correct Answer Incorrect Answer

      Solution

      The speed of sound in air at room temperature (20°C) is approximately 343 m/s.   This speed depends on the temperature and medium.   As temperature increases, the speed of sound also increases.   This is because the molecules in the air move faster, allowing sound waves to propagate more quickly.
