Properties of Matter & Fluids Questions with Solutions
This topic covers the properties of solids and fluids: elasticity, pressure and its applications, Pascal's law, Archimedes' principle and buoyancy, floating and sinking, density, surface tension, capillary action, viscosity and Bernoulli's principle. Exams test everyday examples: a hydraulic lift works on Pascal's law, ships float because of Archimedes' principle, raindrops are spherical because of surface tension, and kerosene rises in a lamp wick by capillary action. Also know why it is easier to swim in sea water (greater density and buoyancy). Practise the properties of matter questions below, written in the style of the general awareness sections of exams such as SSC, banking, railways, CUET GAT, MAH CET and CLAT. Each question comes with a detailed explanation that adds related facts, so every question helps you revise more than one point.
