Do all liquids (for example glue, peanut butter) dry out at some point and why?
In: Chemistry
Some materials dry out, or lose water to vaporization, leaving the solute behind.
Some liquids really don’t dry out complete due to colligative properties, the vapor point changes, or a liquid that was in the mixture that was not water and doesn’t boil at normal Earth conditions – think sticky coke spills that never seem to go away.
Some materials are actually hygroscopic and absorb moisture from the air. Usually not a problem, but in Chemistry you have to account for the mass or remove it
All liquids can change state. A liquid (in your post you are actually reference mixtures, not compounds), can also exist as gaseous, or solid. However, do the conditions exist in our universe for all elements and compounds to undergo phase change to gas or solid from liquid? That I don’t know. You would have to look at all the charts for all elements and compounds and then look through the entire universe for all temperatures and pressures to see if there exists an element or compound that is only liquid throughout the complete range of temperatures and pressures in the universe.
Not everything(i.E glycerin, galinstan etc)
Most things tend to rot before they dry out but if you’d let them just there long enough the water inside would evaporate which already happens at room temperature.
