Question

review it!
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?
shape of the substance
volume of the substance
particle arrangement of the substance
mass of the substance

Explanation:

To determine the factor affecting the state of matter and wave travel, we analyze each option:

• Shape: A substance's shape is more about its external form, not the state of matter (solid, liquid, gas) or wave propagation.
• Volume: Volume is the space occupied, but the state of matter (e.g., solid has fixed volume, gas does not) is determined by particle arrangement, not volume itself dictating the state.
• Particle arrangement: The state of matter (solid: closely packed, liquid: less packed, gas: widely spaced) is determined by how particles are arranged. This arrangement also affects wave travel (e.g., light and sound interact differently with solids, liquids, gases due to particle spacing and bonding).
• Mass: Mass is the amount of matter, not related to the state of matter (a substance can have the same mass in different states) or wave travel through a medium.

So the correct factor is particle arrangement.

Answer:

particle arrangement of the substance
