How can a model can be used to develop a testable hypothesis? Conceptual models are never revised once they are made.

Conceptual models cannot be used to develop a testable hypothesis.

Conceptual models help us see how things are related and how they connect or
work together. This helps us develop a hypothesis based on changes in a variable and the corresponding response of another variable.

Conceptual models are not based prior observations and are guesses used to generate a hypothesis.

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
