Why does cold water have more molecules than hot water?
You may want to frame this question in this manner, "Why does cubic unit of cold water have more molecules than same cubic unit of hot water" This is so because heat causes movement in molecules and malkes them move apart. Hence the hotter the water, the further apart the molecules. Therefore, cold water has more molecules than hot water of same unit.
Are molecules close together in a liquid?
molecules are closer together in a liquid than a gas but further apart than in a solid
Why do large groups of sugar molecules break apart in water?
when sugar dissolves in water the sugar molecules are more attracted-to the water than each other.the molecules-break apart from each other and water molecules surround them.
Are molecules in cool substances closer together than in hot substances?
Yes, they are. Molecules get further apart as they gain energy.
Do molecules get closer together as water is heated Yes or No?
No, ice expands because the molecules are farther apart.
Why water expands on solidification?
due to hydrogen bonding bettween water molecules.
Are particles in a gas or a liquid further apart?
The molecules in a gas are spread further apart than those in a liquid.

Does sound travel faster than air or water?
Water. Sound is a vibration of molecules, and in air, the molecules are further apart than in water, so the sound wave needs less energy to move each particle away from the source.

What are examples of practical applications for density?
An example of real life density is "ice floating on water." Ice floats on water because it is less dense than water. Things that are less dense float on top of things that are more dense because molecules in ice are further apart than molecules in water.
Do molecules get closer together as water is heated Yes or No?
No, ice expands because the molecules are farther apart.
Why 1 gram of steam has a volume about 1000 times the volume of one gram ofwater?
Simply because - due to the addition of heat, the water molecules in steam are further apart than those in cold water.
Are gas molecules further apart than solid molecules and liquid molecules?
Generally, the molecules in gases are further apart than molecules of the same substance in either liquid or solid state. However, note the existence of a critical temperature for each substance. Above the critical temperature, no liquid or solid phase can exist, but it would be theoretically possible to compress a supercritical substance so that it would have closer molecules than some liquid form of the same substance.
What happens when warm air molecules move farther apart?
When air warms the molecules on average move more quickly. If the volume occupied remains the same then the average distance apart remains the same, if the pressure remains the same the air will expand and this means that the air molecules will get farther apart.
