Final answer:
Models are representations that have limitations in accurately describing reality. Assumptions and simplifications in scientific models can limit their explanatory power. For example, the planetary model of the atom helps explain certain observations but doesn't capture the true complexity of electron behavior.
Step-by-step explanation:
A model is a representation of something that is often too difficult to directly observe or display. In the context of scientific models, there are certain approximations and assumptions that can limit their explanatory power. For example, the planetary model of the atom, where electrons are pictured as orbiting the nucleus, is a simplified representation that helps explain certain observations, such as the emission of light from hot gases. However, this model doesn't accurately depict the true complexity of electron behavior in reality. Another limitation of models is their dependence on language, as ordinary terms may not fully capture the intricacies of complex phenomena. It's important to recognize the limitations of models, so as not to form incorrect ideas or conclusions based solely on their representations.
