Temperature (oC) Vapor pressure (kPa)
0 0.61
20 2.33
60 19.92
100 101.3

Yes, endothermic means it turns cold. and some chemical changes include change of tempature.

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.
