Question

Why are solids incompressible?

Short/Brief Note
Advertisements

Solution

The intemuclear distance between the constituent particles (atoms, molecules or ions) in solids are very less. On bringing them further closer, there will be large repulsive force between electron clouds of these particles. Therefore, solids cannot be compressed.
