Question

refer to the table below when answering the following question. table 1.6 densities of some common materials substance density (g/cm³) substance density (g/cm³) ice (0°c) 0.917 human fat 0.94 water (4.0°c) 1.0000 cork 0.22 - 0.26 gold 19.31 table sugar 1.59 helium (25°c) 0.000164 balsa wood 0.12 air (25°c) 0.001185 earth 5.54 according to the data, which medium would allow sound waves to travel the fastest? ice air earth gold

Explanation:

Sound waves travel faster in denser media. Among the given substances, gold has the highest density ($19.31\ g/cm^{3}$) as per the table. Higher density generally means particles are closer together, allowing sound - wave energy to be transferred more quickly.

Answer:

D. gold
