Mike Blaber (Florida State University) 11.1: A Molecular Comparison of Gases, Liquids, and Solids is shared under a license and was authored, remixed, and/or curated by LibreTexts. The state of a substance depends on the balance between the kinetic energy of the individual particles (molecules or atoms) and the intermolecular forces.

Sep 7, 2023 · In this video they have two substances of different densities that "float" on liquid carbon dioxide at 28 o C and 69 bar, but one is more dense than supercritical carbon dioxide. They then raise it to the critical point 31.1 o C and 73.9 bar and the phases merge, with the one float sinking, and the other moving around. They then return to the ...
May 19, 2017 · Hope this helps :) Solids - vibrational (and rotational); moving very slowly. Liquids - vibrational, rotational, and translational; moving quickly. Gases - vibrational, rotational, and translational; moving very quickly. Particles are always moving. No matter what. There is a certain point where they move so slowly it is considered minuscule ...
Nov 21, 2023 · Liquids have a bit more space in-between each molecule than solids. Liquid molecules also move a bit faster than solids, and they will simply flow past other molecules within the container.

11.2.4 Hydrogen Bonding. hydrogen bonding – special type of intermolecular attraction that exists between the hydrogen atom in a polar bond and an unshared electron pair on a nearby electronegative ion or atom. hydrogen bond with F, N, and O is polar. density of ice is lower than that of liquid water.
As a result, the particles in a liquid move faster in terms of vibration, rotation, and translation. Because they are moving faster, the particles in the liquid occupy more space, and the liquid is less dense than the corresponding solid. Differences in kinetic energy alone cannot explain the relative densities of liquids and solids.

Aug 17, 2022 · This explains why liquids can be compressed and poured. In a liquid, the particles move continually with random motion. When a liquid is heated the particles gain energy and are able to move faster. Therefore, the hotter the liquid the faster the movement. This faster movement causes the forces of attraction between the particles to become weaker.
