Question

which of the following determines the state of matter of a substance and affects the way light waves and sound waves travel through a medium?
the particle arrangement of the substance
the mass of the substance
the shape of the substance
the volume of the substance

Explanation:

The state of matter (solid, liquid, gas) is determined by how particles are arranged. In solids, particles are closely packed; in liquids, they are less tightly packed; in gases, they are far apart. This particle arrangement also affects wave - travel. For example, sound travels faster in solids (closely - packed particles) than in gases (loosely - packed particles). Mass, shape, and volume do not determine the state of matter or have a direct fundamental impact on wave - travel in the way particle arrangement does.

Answer:

the particle arrangement of the substance
