Vedclass · Answer

(A) One $Pascal$ $(Pa)$ is the pressure exerted by a force of one $newton$ $(N)$ on an area of one square meter $(m^2)$.Atmospheric pressure is defined as the force per unit area exerted by the weight of the atmosphere.The standard value for one atmospheric pressure in terms of $Pascal$ is $1 \ atm = 101325 \ Pa$.Since $1 \ kPa = 1000 \ Pa$,we have $1 \ atm = 101.325 \ kPa$.
