What does «expansibilidad» mean in Spanish?
- The tendency for the volume of a gas to expand due to repulsive forces between its molecules. Gases have the property of occupying the container that contains them, trying to occupy as much space as possible. This is because the forces holding the gas molecules together are negligible (considered to be zero). These molecules move in a disorderly manner in all directions in lines, even colliding with each other and against the container that contains it. This simultaneous collision of molecules against the walls of the containing vessel generates a certain force per unit area called gas pressure.
- Quality of something that is expandable, that can expand.
