Question

what would increase the speed of a sound wave?
a wave passes from a solid to a liquid while remaining the same temperature.
the medium increases in temperature while remaining the same phase.
the medium decreases in temperature while remaining in the same phase.
a wave passes from a liquid to a gas while remaining the same temperature.

Explanation:

The speed of a sound wave depends on the properties of the medium. In general, sound travels faster in solids than in liquids, and faster in liquids than in gases. Also, the speed of sound in a medium increases with an increase in temperature. When a wave passes from a solid to a liquid while maintaining the same temperature, the speed decreases. When the medium increases in temperature while remaining in the same phase, the speed of sound increases. When the medium decreases in temperature while remaining in the same phase, the speed of sound decreases. When a wave passes from a liquid to a gas while maintaining the same temperature, the speed decreases.

Answer:

The medium increases in temperature while remaining in the same phase.
