which state of matter model matches the characteristics given below? 1) have strong molecular attractions 2) have a high density
Answer
Answer:
B.
Explanation:
Step1: Analyze solid - state properties
Solids have strong molecular attractions which hold the molecules in a fixed position. This strong intermolecular force is responsible for their definite shape and volume.
Step2: Consider density in solids
Due to the close - packing of molecules in solids, they have a high density compared to liquids and gases. In the given models, model B shows closely packed molecules which is characteristic of a solid. Model A shows molecules that are far apart (like in a gas), and model C shows molecules that are more spread out than in a solid but less than in a gas (like in a liquid).
