    physical property is related to the use of Activated charcoal in gas masks is Physical adsorption

    Explanation:

    Respirators in the gas masks has a 2-stage inhalation protection process. In the first step, particle filter is used that behaves like a physical barrier that removes bacteria from air which is inhaled. When the bacteria is inhaled, it gets entangled in the filter fibres preventing it from being inhaled into the lungs.

    In the next stage, activated charcoal is used. This layer with highly porous charcoal attracts and binds to toxins. Through adsorption process, a solid or a liquid can trap particles on its surface. Toxins that pass through the charcoal become bonded to its surface, preventing inhalation of the toxins.
