Verified step by step guidance1
Understand that pressure is defined as force applied per unit area and is a measure of how much force is exerted on a surface.
Recall the common units used to measure pressure, such as atmospheres (atm), pascals (Pa), torr, and millimeters of mercury (mmHg).
Recognize that mol (mole) is a unit for the amount of substance, not pressure.
Recognize that L (liter) is a unit of volume, not pressure.
Recognize that K (kelvin) is a unit of temperature, not pressure, so the correct unit for pressure among the options is atm (atmosphere).
