sound will travel slowest through which medium?\no water at 55°c\no water at 75°c\no ice at 0°c\no ice at…

Brief Explanations:

Sound travels slower in less - dense and more disordered media. Water is less dense than ice and as temperature increases in water, its density decreases and molecular motion increases which slows sound. Among the given options, water at higher temperature is the least dense and most disordered for sound propagation.

Answer:

water at 75°C
