B. The lines show where a phase change happens to a substance
Ability to moderate temperatures is not a property of water
Answer: Mothballs have weak intermolecular forces.
No all substances do not behave like mothballs at normal conditions. Example: benzene , chloroform
Explanation:
Sublimation is a process of converting a substance from solid state to gaseous state without the formation of liquid at constant temperature.
A substance which undergoes sublimation is called as sublimating substance.
As mothballs is made of napthalene which has weak inter molecular forces of attraction between its molecules, it directly sublimes into gaseous state without leaving any residue and is called as a sublimating substance.
Not all substances behave like mothballs at normal conditions. Example: benzene , chloroform
1. air components change from place to place, while water will just stay the same
2. Water doesn't have nor show individual properties, but air does show that it has it's own property
3. You can separate different gases from air physically, but with water you must pass electricity through it.
Don't take my word for it, this is just what I learned back in middle school.
