Answer: The medium increases in temperature while remaining in the same phase.
Why: Sound speed depends on the medium's stiffness and density (c = √(stiffness/density)). For an ideal gas c = √(γRT/M), so raising temperature increases c (∝√T). Passing from a solid→liquid or liquid→gas at the same temperature generally reduces stiffness relative to density and so lowers the speed. Lowering the temperature (same phase) reduces c for gases (and typically for everyday liquids), so that also does not increase the speed.
