Liquid
In this state of matter the volume is fixed but size is not for mutual attraction force in their molecules is weaker then solids. the density of the fluid is more then gas and less then solid.
Water is a liquid. The shape of the liquid is not fixed. It takes the shape of its character. Liquid can flow. liquid can be poured or dispersed. The Properties of liquid are intermediate between those of solid or gas. The intrauterine forces of the liquid are weaker then the solid but stronger then the gases.
The position of the constituent particles in the liquid is not as fixed as that of the solid, but they are free to move like as gases. The intrauterine forces in the liquid and stronger then gases.
The constituent particles of a liquid break apart from each other into molecules and atoms and are attracted to other molecules. If an attracted to another molecules. If an attempt is made to pressurize the molecules like a solid.
Mechanical Properties Of Fluids
Fluid
The substance that can flow is a liquid since it cannot maintain stress, it assumes the shape of the same vessel in witch it is placed. Both liquid and gas are liquid.
Pressure
The thrust, which is applied per unit area of a surface, is called pressure. If the entire force (F) is normally on a plane area (A)
The Pressure will be P = F/A.
Pressure is a scalar quantity. The SI unit of pressure is = Nm-2 or Pascal (Pa). The CGS unit of pressure is = dyen The Pressure increase as the area decrease.
1. The type of the wheels of heavy vehicles are made quite wide, because the area of the wheels is wider then type of the wheel of heavy vehicles.the pressure on the road or ground (P = F / A)
2. Camel move easily in the desert, because by the formula, pressure force / area, the feet of the camel are wide because of their area.
3. The surface area of sharp knife cutting edge is very small so that more pressure can be applied to cut the meat.
