Explanation
Pressure is measured in pascals, named after French scientist Blaise Pascal, with one pascal defined as one newton of force applied over an area of one square meter. Because a single pascal represents a relatively small amount of pressure, larger everyday values, such as atmospheric pressure or tire pressure, are often expressed in kilopascals or other related units. Pascal’s principle, which describes how pressure is transmitted through a confined fluid, is named after the same scientist. Explore more Everyday Science MCQs on mcqstutor to keep practicing.
