Define Pascal’s law and state the factors affecting the pressure
Answers
Explanation:
Pascal's law (also Pascal's principle or the principle of transmission of fluid-pressure) is a principle in fluid mechanics given by Blaise Pascal that states that a pressure change at any point in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere.
Factors Affecting Air Pressure:
Temperature: As the temperature increases, air expands because of which its density decreases which results in low pressure.
Height from Sea Level: Air pressure is created due to weight of air therefore sea level has highest air pressure.
Moisture in Air (Humidity): Conversion of water from liquid state to gaseous state because of evaporation is known as atmospheric humidity.
