Why are liquids viscous and solids elastic?
You’ve probably learnt that solids have a fixed shape and volume whereas liquids only have the latter. But why is that? In this blog you will learn how a key liquid property; it’s viscosity — emerges from interactions between molecules. You will also learn why viscosity is fundamentally different from elasticity and why this is the underlying reason that liquids differ from solids. Let’s illustrate this through an…
