A hydraulic press is based on the principle of-

Explanation

Concept: Pascal’s principle: Pascal’s Law is the principle of transmission of fluid-pressure. It says that "a pressure exertedanywhere in a point of the confined fluid is transmitted equally in all directions throughout the fluid ”. Hydraulic Lift : The lift that uses pascal's law and used to lift objects with the help of fluid is called hydraulic lift. It works on Pascal's law. Important Points Boyle’s, Charles’, and Gay Lussac's Laws describe the basic behavior of fluids with respect to volume, pressure, and temperature. Gay Lussac’s Law It states that at constant volume, the pressure of a fixed amount of a gas varies directly with temperature. P ∝ T Boyle's Law For a fixed mass of gas at a constant temperature, the volume is inversely proportional to the pressure. PV = constant (If the temperature remains constant, the product of pressure and volume of a given mass of a gas is constant.) Charles' Law For a fixed mass of gas at constant pressure, the volume is directly proportional to the Kelvin temperature. ​ = T P Const P ∝ ​ V 1 V ∝T or, ​ = T V Const
