Question

What properties of solid and liquid are the same?
A) Volume
B) Shape
C) Random packing
D) None of these

Answer 1

Hint: Both solid and liquid have almost stronger to moderate intermolecular attraction than gases. Packing depends on the position of particles or their arrangement in the particular matter. In gases particles are free to move anywhere since no random packing is there in gases.

Complete step by step answer:
Let’s compare the properties of solid and liquid so then it is easy to answer this question.
- Solid, liquid and gas are different states of matter.
- Solid has strong intermolecular attraction that holds the particles present in a particular solid whereas Liquid has moderate intermolecular attraction since they have loose packing as compared to solid.
- Solids have their own shape and volume regardless of the container, whereas liquids can maintain their volume but since particles can flow in liquid thus the shape of the liquids can be retained.
- Solids are incompressible as the packing in solid is tight and molecules are packed in an ordered manner, whereas it is easy to compress liquids as the particles in liquids are easy to flow and move which can be compressed easily due to loose packing.
- Diffusion in liquids is easy as compared to solids.
- Density for both solids and liquids are high as compared to gases.
Option A) this is a correct option as we have studied above that solid can have its own shape and volume regardless of the container and Liquids can also maintain their volume but a liquid changes the shape once placed in different containers.
Option B) This is an incorrect option as solids can have their own shape, but in liquids the shape gets changed once they place themselves into different containers.
Option C) this is an incorrect option ,since packing in solids is strong whereas liquids has moderate packing as compared to solids. In solids particles are packed in ordered arrangement whereas in liquid, particles are free to move.
Option D) is incorrect since Option A is right.
Hence, the correct answer is, ‘Option A’.

Note: In gases diffusion is easy as the particles are so randomly arranged in comparison to solid followed by liquid. Gas has generally lower density than solid and liquid. Also gases can be compressed easily.
