Which statment best describes the collision of gas particles according to the kinectic-molecular theory

As particles travel in straight lines, their paths sometimes meet, and then they bounce apart with no gain or loss of energy. hope this help:)

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.
