Liquid is defined as a material which will take the shape of the container. It is one of the three classical states of matter.
Examples: water, ethanol, most of the organic solvents.
Mechanical properties:
Volume: Commonly liquids are measured in the units of volume. SI units for volume are m3.
Pressure:
Hydrostatic head is the main property of the liquid. This hydrostatic head is calculated as P= h*rho*g. h = height of the liquid column, rho = density of the liquid, g = acceleration due to gravity.
Examples: water, ethanol, most of the organic solvents.
Liquids tend to have better thermal conductivity than gases, and the ability to flow makes a liquid suitable for removing excess heat from mechanical components. The heat can be removed by channelling the liquid through a heat exchanger, such as a radiator, or the heat can be removed with the liquid during evaporation
Liquid is the primary component of hydraulic systems, which take advantage of Pascal's law to provide fluid power. Devices such as pumps and waterwheels have been used to change liquid motion into mechanical work since ancient times. Oils are forced through hydraulic pumps, which transmit this force to hydraulic cylinders. Hydraulics can be found in many applications, such as automotive brakes and transmissions, heavy equipment, and air-plane control systems. Various hydraulic presses are used extensively in repair and manufacturing, for lifting, pressing, clamping and forming
