middle box 1 - liquid
middle box 2 - temperature
left box 1 - fastest
right box 1 - gas
right box 2 - slow
Explanation:
Sound is a longitudinal wave i.e cannot travel through vaccuum. It travels the fastest in solid, fast in liquid and slowest in gas due to the arrangement of molecules in the 3 states of matter. It varies with temperature. The speed is proportional to the square root of the absolute temperature, giving an increase of about 0.6 m/s per degree Celsius.
