Definition of Comparison of solid, liquid and gas
Check what you remember
Read the wording for your board, then hide it and explain Comparison of solid, liquid and gas in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: OCR
In the solid, particles vibrate about fixed positions and energy is localised, giving low entropy; in the gas, particles move freely throughout the container and energy is dispersed over many arrangements, giving high entropy.
