Sound — practice question

The speed of sound varies between different states of matter. In water, the speed of sound is $1500\ \text{m s}^{-1}$. Which row gives the correct comparison of the speed of sound in ice and the speed of sound in steam when each is compared with the speed of sound in water?

  • Aspeed of sound in ice: less than $1500\ \text{m s}^{-1}$; speed of sound in steam: less than $1500\ \text{m s}^{-1}$
  • Bspeed of sound in ice: less than $1500\ \text{m s}^{-1}$; speed of sound in steam: more than $1500\ \text{m s}^{-1}$
  • Cspeed of sound in ice: more than $1500\ \text{m s}^{-1}$; speed of sound in steam: less than $1500\ \text{m s}^{-1}$
  • Dspeed of sound in ice: more than $1500\ \text{m s}^{-1}$; speed of sound in steam: more than $1500\ \text{m s}^{-1}$
