What is the spreading out of a substance?
A non-solid. The particles are really spread out in a gas, and less spread-out in a liquid.
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.
Why do things melt?
their temperature rises above their meting points. This causes the particles to vibrate so fast that that all spread apart, causing a liquid to form.
What is the difference between diffusion and dissolve?
Diffusion is the spread of particles from an area of higher concentration to an area of lower concentration. Diffusion can occur in gas or liquid.Dissolving occurs when one substance, the solvent, supports the particles of another substance, the solute, to form a solution. The two processes are similar.Example:Sugar in the bottom of a cup of coffee will slowly diffuse into the bottom of the cup dissolving as it goes. When we stir the coffee we make the process faster and the dissolving is uniform without a higher concentration at the bottom of the cup.Perfume or petrol (gasoline) in a container in the corner of the room will slowly diffuse out and we can smell it even when we are not next to the container. Again the concentration is higher the closer we are to the container.
Are gas particles packed close together?
No, they are spread out. Gases are less dense than solids and liquids, which is caused by the particles being spread out.

Why do certain smells spread through the air faster than others?
Well, it depends on the heat of the air and how much air there is. Smells spread though the air during the process of diffusion, which happens faster if the air is hotter(the particles of the air will move faster if hotter and therefore the substance will diffuse quicker). Also they will spread faster if there is more air, which means more particles being able to diffuse the substance. I hope that this helps. As you can see, I an an a* student in chemistry! Please feel free to correct and extend if needed.
What becomes bigger in size due to movement of particles in a solid?
If the particles in a substance are moving, the volume of that substance becomes larger because the particles move faster and spread farther appart. the mass of the object stays the same because it is the same amount of particles, just in a format in which the volume is larger. hope i helped :)
Are liquid particles spread apart?
yes. solids are more dense than liquids and the particles in gases are more spread out and faster.
What do you call the substance in witch particles are being spread out?
it is called a liquid
What does the sun do to make the water change state?
The sun heats up the water causing particles to move faster and spread apart. this changes water to a gas state and becomes clouds.
What makes patrticles spread out faster in hot water then in cold water?
In warmer water, particles generally have more energy. This makes them move faster, and so spread out faster.
If a liquid with large particles is shaken until all particles are dissolved what is the new substance?
There is no new substance; it is just mixed up and all the atoms are spread out so you can't see the individual particles.
As the thermal energy of matter increases, its particles usually spread out, causing?
thermal expansion.
What happens to the particles of solid turned into gas?
The particles spread apart, making the substance less dense. The particles also spread apart to fill more space. Also, the movement of said particles become more active.
What is the spreading out of a substance?
A non-solid. The particles are really spread out in a gas, and less spread-out in a liquid.
How does the arrangement and movement of particles change as a substance changes from a liquid to a gas and solid to a liquid?
From a liquid to a gas, the particles become more spread out and move slower. From a solid to a liquid, the particles also become more spread out and move slower.
