We can measure viscosity by measuring the rate at which a metal ball falls through a liquid (the ball falls more slowly through a more viscous liquid) or by measuring the rate at which a liquid flows through a narrow tube (more viscous liquids flow more slowly). The viscosity of a liquid is a proportion of its protection from deforming at a given rate. Hydrocarbons undergo combustion in the presence of air; Complete combustion occurs to form water and carbon dioxide gas; Carbon and hydrogen from the fuel are oxidised / gain oxygen: Viscosity is the propensity of a liquid to oppose any adjustment in its shape or movement. Viscosity denotes opposition to flow. Viscous (Viscous) ka angrezi mein matalab arth aur proyog For example, if a substance is incompressible (solid and liquid) the density is considered constant at a given temperature and pressure, and can be used to identify a substance (gold has a density of 19. A viscous liquid is thick and…. tdngpr yffjv tzlgg jltpcvf jdsvu javdglv wvmie bfm zzsqgp xtchl
