1.. Density or Mass density(ρ) : The density of a fluid is defined as the ratio of the mass of the fluid to its volume of fluid. Density is a crucial property that defines how much mass is packed into a given volume of a substance. It is expressed as the...
The alcohol is used in manometers instruments because A) Due to low vapour pressureB) As it is clearly visibleC) As it has low surface tensionD) It can easily provide longer column due to low densityAns: D 2. When no resistance is encountered by displacement, then such a substance is known...
