Unlike solids, fluids (liquids and gases) lack a definite shape and offer very little resistance to shear stress. This ability to flow and deform continuously under applied force is what characterizes &#8220;fluidity.&#8221; In the NEET syllabus, understanding the microscopic differences\u2014where liquids are nearly incompressible due to strong intermolecular forces while gases are highly compressible\u2014is fundamental for solving higher-order problems.<\/p>\n\n<div class=\"grid-container\">\n<div class=\"mini-card\">\n<span class=\"card-title\">DENSITY (&rho;)<\/span>\n<p class=\"card-body\">Mass per unit volume.
