Definition of pascal in chemistry
WebThe definition of a pascal is as follows: The pascal (symbol Pa) is the SI unit of pressure.It is equivalent to one newton per square metre. The unit is named after Blaise Pascal, the eminent French mathematician, physicist and philosopher. Definition: Inch of mercury. Inches of mercury or inHg is a non-SI unit for pressure. WebPressure is dependent on both the force exerted and the size of the area to which the force is applied. We know from Equation 6.2.1 that applying the same force to a smaller area produces a higher pressure. When we use a hose to wash a car, for example, we can increase the pressure of the water by reducing the size of the opening of the hose with a …
