Air expands due to high temperature water. And nothing happens to the molecules. As they move faster usually from increased temperature, they become farther apart.

Wiki User
∙ 13y agoWhen they get cold and solid the molecules move together and get tightly packed and move very slowly. When very hot they spread out (gas) and move very fast.

Why does water expand at the equator?
Water expands at the equator because it is warm there, and warm molecules expand. Warm molecules expand and cold molecules decrease in size.
How does the temperature of the air molecules change at each level of the atmosphere?
The air molecules expand as it gets higher and higher into the atmosphere. the molecules expand.
What do substances do when heated because of the molecules?
they expand
How does heat maike objects expand?
Yes, the more temperature an object has the farther apart the molecules move.
How much does an iron casting expand when heated?
because molecules dissolve or melt during the process and expands.
Why does water expand at the equator?
Water expands at the equator because it is warm there, and warm molecules expand. Warm molecules expand and cold molecules decrease in size.
What happens to most substances when they are heated?
They expand due to the molecules speeding up.
How does the temperature of the air molecules change at each level of the atmosphere?
The air molecules expand as it gets higher and higher into the atmosphere. the molecules expand.
When the pressure inside a container increases due to heat is it because molecules expand?
No, molecules do not expand but they DO move around quicker.
Why does breast milk shrink when frozen and expand when thawed?
Any liquid or solid shrinks when frozen; the molecules contract. Molecules expand when thawed.
Will heat make a ball bounce higher?
Yes, because the gas molecules in the tennis ball expand. When the molecules expand there energy increases.
What do substances do when heated because of the molecules?
they expand
Why do objects expands when heated?
They expand because their molecules vibrate more rapidly resulting in more space between the molecules which makes the object expand.
Will an aluminum door expand in the summer or winter?
It will expand in Summer as the heat makes the aluminum molecules move faster causing them to expand
In which state of matter do the particles expand to fill all the space?
In the gas state of matter the molecules are moving too fast to stick to other molecules. Because they are free floating the molecules expand to fill all of the space available.
Why does water expand when cold?
Water expands when it is cold because the water molecules found in water expand in the cold.
In state of matter do the particles expand to fill all the space available?
In the gas state of matter the molecules are moving too fast to stick to other molecules. Because they are free floating the molecules expand to fill all of the space available.
