Yes, ok take a block of ice for an example, when the water is frozen into the ice cube the molecules slow downcget closer and they can't move, when you melt the ice, or it is heated, then the molecules spread out and get faster making it a liquid.

What happens to molecules in a heated fluid?
Molecules will rapidly spread apart and move in every direction in the presence of a heated fluid, and tightly bunch up in cooler fluids.
What is it called Fewer molecules spread apart?
When a liquid or gas is heated, the molecules move faster, bump into each other, and spread apart. Because the molecules are spread apart, they take up more space. They are less dense. The opposite occurs when a liquid or gas is cooled.
Do molecules rise or sink after they are heated?
Rise
What happens to the molecules in a balloon when they are heated?
they pop
The spread of molecules throughout an area?
i think is the isotonic .. Diffusion is the spread of molecules. Osmosis is the movement across water.
What happens to liquids and gases as they are heated?
The molecules in side move or spread apart
What happens to molecules in a heated fluid?
Molecules will rapidly spread apart and move in every direction in the presence of a heated fluid, and tightly bunch up in cooler fluids.
When a gas or liquid is heated is its mass increased?
no, but the molecules spread out. so it appears the mass has increased, but it hasn't.

When molecules in liquids and gases are heated they?
When molecules in liquids and gases are heated they move faster
How does the speed of molecules of gas change when heated?
The speed of the molecules speeds up when the gas is heated.
Does atoms and molecules of gases and liquids are heated they sink?
after atoms and molecules of gases and liquids are heated, they sink?
What happened to the water molecules when they are heated?
the molecules evapourate
Why do molecules move when heated?
So when molecules are heated, the heat is so intense that they have to move around for them to cool down.
When air is heated air pressure decreases because the molecules?
when air is heated ,air pressure decreases because the molecules are
What are your rocks and soil heated by?
Rocks and soil are heated by two things, atoms and molecules. when they get heated they vibrate and sends heat to other atoms or molecules in the same substance until the whole thing is heated. The energy comes from the sun, but the atoms and molecules really heat them.
How does heat affect the molecules in a substance?
They rapidly vibrate. Yes, they do, but how rapidly depends on the amount of heat (kinetic energy) added to the molecules. If solid, they will eventually melt depending on which solid and what its melting point is. If liquid, they will eventually become a gas or vapor, and a gas will expand indefinitely into the atmosphere if not contained within something. Think of water: ice heats to liquid water which in turn becomes steam (vapor) which goes out into the atmosphere unless it is contained. If the container cannot expand and the water vapor (or any other gas) continues to be heated, eventually the gas will cause the container to explode because the internal pressure will exceed the ability of the container to hold it.
