SC.8.P.8.1-Exceeding Practice Sheet

Level:
Description:
Developing Identify the states of matter and their characteristics (e.g., movement, volume,
shape).
Achieving Identify the states of matter and describe their characteristics and the transition
between states (e.g., melting point, boiling point, freezing point).
Exceeding Describe the states of matter, their characteristics, the transition between states
(e.g., melting point, boiling point, freezing point) and predict how they may
interact in real world scenarios.
Example Questions:
Liam is constructing a model showing how a sound wave travels through a solid, liquid and gas.
He understands there is a relationship between the speed of the wave and the type of medium (or
material) it travels through. Based on your understanding on the different states of matter, how
would a sound waves speed change between a gas, liquid and sold? Why does the speed change?

Answer 1

The speed of a sound wave changes depending on the state of matter it travels through. It is fastest in a gas, slower in a liquid, and slowest in a solid.

Step-by-step explanation:

The speed of a sound wave would change between a gas, liquid, and solid. In a gas, sound waves travel faster because the particles are spread out and can vibrate more easily. In a liquid, the speed of sound is slower than in a gas because the particles are closer together and it takes longer for the vibration to travel through the medium. In a solid, sound waves travel even slower because the particles are tightly packed and the vibrations have a shorter distance to travel.
