which change will decrease the speed of a sound wave traveling through a gaseous matter?\nreplacing the gaseous matter with a liquid\nreplacing the gaseous matter with a solid\ndecreasing the temperature of the matter\nincreasing the temperature of the matter

Answer

Brief Explanations:

The speed of sound in a gas is directly proportional to the square - root of its temperature. Also, sound travels faster in solids and liquids than in gases. Decreasing the temperature of the gas will decrease the kinetic energy of gas particles, reducing the speed of sound.

Answer:

C. decreasing the temperature of the matter
