\nThe correct answer is (C) 1500 m\/s.
\n<\/section>\n
\nThe speed of sound varies significantly depending on the medium and its temperature. Sound travels faster in denser media (liquids and solids) compared to gases because particles are closer together, allowing vibrations to be transmitted more quickly.
\n<\/section>\n
\nAt 20\u00b0C, the speed of sound in air is approximately 343 m\/s. In pure water at 20\u00b0C, the speed of sound is typically around 1482 m\/s. Option (C) 1500 m\/s is the closest approximation among the given choices for the speed of sound in water at this temperature. The speed of sound in solids like steel can be much higher, around 5000-6000 m\/s.
