state occupation of phases

Postby Ryan Yoon 1L » Fri Feb 07, 2020 11:38 am

Why do gas molecules occupy more space then liquid and solid phases?

Gas molecules are higher energy and occupy the entirety of the volume of a container as they 'bounce' off of one another and off of the container; it has a lot to do with the decreased density and the increased speed of the particles when they're in their gaseous phase.

Gas molecules "occupy more space" since they have a higher entropy, meaning higher disorder, so their location at a given time is less known.

Solids and liquids have less energy, so they are more tightly packed and thus take up less space than gases, which have more energy and are liable to move around more.

Gasses have higher entropy, while solids and liquids have their molecules tightly packed. Gas molecules can be in any location, since they are not tightly packed, which is why they "occupy more space"

Think of it as what happens at each phase change. For example, you can hold an ice cube because it's solid and compact. When the ice melts it becomes water and it gets harder to contain. And when it becomes a gas (because of boiling) you can't really contain a gas because it diffuses throughout the area it has to work with. In terms of what we learned in class, gases occupy more "space" because they have higher entropy than liquids or solids.

Gases have their molecules a lot more spread out, liquids are only slightly spread out, and solids have their molecules tightly packed.

In gases, the kinetic energy is higher than the intermolecular forces between them, allowing them to spread out unlike solids and liquids. Therefore, they take up more space since the individual gas molecules are bouncing all over the place.
