Pressure is defined by the forces exerted by the particles on the wall after the collision. When 653 mm Hg pressure is converted to SI unit then it equals 87,058 Pa. Thus, option B is correct.
The International System of Units is the system of measurement that is abbreviated as SI and ensures the worldwide applicability of the metric system. Pasacal (Pa) is the SI unit of pressure.
Pascal is the SI unit that measures the pressure and can be determined by the value given in mmHg.
It is known that 1 mmHg = 133.322 pascals (Pa) pascal value
1 atm = 760 mmHg = 101325 Pa
Given,
Pressure = 653 mm Hg
Substituting values in the unit conversion system the pressure in Pa can be calculated as,
(101325 Pa × 653 mm Hg) ÷ 760 mmHg
= 87,058 Pa
Therefore, option B. 87,058 Pa is the pressure in the SI unit.
