A dry sponge removes soot via which process?

When a dry sponge removes soot, it primarily utilizes the process of adsorption. Adsorption occurs when particles, like soot, adhere to the surface of a material without being absorbed into its structure. The sponge's porous surface provides an area for the soot particles to cling to, effectively capturing them.

Unlike absorption, where a substance is taken into the material and typically undergoes a transformational change, adsorption involves a physical interaction between the soot and the surface of the sponge. The effectiveness of a sponge in removing soot can be attributed to its properties, allowing it to trap particles on its surface rather than absorbing them into the sponge's material.

This distinction is crucial in restoration processes, particularly in fire and smoke damage scenarios, where understanding particle behavior can significantly improve cleaning techniques and outcomes.
