What happens when you heat or cool molecules?
Heated molecules causes molecules to bounce into each other separating them. As molecules separate, their density, the amount of matter found in a given volume or space, decreases. Cooled molecules are not that loose and start to get packed together if it gets frozen. -twocute
What happens to the molecules of a liquid when it is cool?
When ice cools it shrinks
How do molecules react when they are allowed to cool?
There movement slows down.
Are molecules in cool substances closer together than in hot substances?
Yes, they are. Molecules get further apart as they gain energy.
What happens when molecule are heated?
Since molecules are particles of matter, it takes energy to move them. Heat is a form of energy. It causes molecules to bounce into each other separating them. As molecules separate, their density, the amount of matter found in a given volume or space, decreases. Air that is heated will rise, therefore, because the gravitational force of the earth on the heated molecules is less than it was on the higher density collection of molecules. Therefore the molecules will spread and become partially flowful- Like the molecules in liquid. They vibrate or move around vigorously depending on their state of matter. If there is enough heat, the intermolecular bonds can break into smaller molecules or separated atoms. And when you cool molecules to 0 degrees Kelvin, you reach Absolute Zero, a point in which the molecules don't move at all.

What happens to molecules asa liquid begins to cool off?
The molecules move slower and slower until the attractive interactions between them become greater than their momentum can withstand, at which point the liquid begins to freeze.
What happens to the molecules of water vapor when the temperature of gas cool to 100c?
The molecules slow down and begin to change back to the liquid state.
What happens to the molecules when a material is heated up or cooled down?
Molecules heat up or cool down. like when you rub your hands together you get warmer and when you go out in the cold you get cold quickly.
Why do space marines cool?
space marines cool because they hot before now they cool.
What happens to air molecules when air gets hot?
The air molecules move farther apart from each other, therefore making it less dense. That's why hot air moves above cool air.
Does warm air contract?
Heat is caused by molecules vibrating and hitting one another. The hotter the air the more the molecules vibrate and the bigger space each molecule needs. This causes the air to expand and its density to fall. As air cools, the vibrations slow down and the molecules need less room. This causes the air to contract and its density will go up.
What happens to molecules in a liquid or gas when they are heated?
when the molecules in a liquid or a gas are heated they move apart, or expand, and the hot, less dense molecules rise and the cold, more dense molecules sink and fill the space then get heated while the hot air that had just went up cool down and they switch doing that as long as the heat source stays. in turn for this switching a convection current starts. ! (p.s im twelve and telling you this but i know what im talking about so this is a completely true explination)
Why sugar dissolves fast on heating?
When sugar is dissolved in any solvent (i.e. Water or Milk), its molecule tries to adjust themselves between the molecules of the solvent... When the solvent is heated the distance between the molecules is increased and the sugar molecules are easily dissolved as compared to when the solvent is cool or at normal temperature...
How is the boiling of water and the cooling of water vapor a reversible reaction?
when water boils the molecules will get a bigger space inbetween them, which forms a gas (water vapor), when you cool down wator vapor the molecules will get closer together and form a liquid (water)
