Why do gases diffuse faster than liquids?
In liquid, there is less space to move so collisions are more frequent between the molecules causing a slower diffusion rate. The opposite happens in gases. There is more space in gases. As a result, there are less collisions between the molecules causing a faster diffusion rate. Other factors that may have an affect on diffusion rates are temperature, mass of the molecule, volume/surface area, and medium used.
Why is the rate of diffusion of gases more rapid than that of liquids?
Gases diffuse faster than liquids because the intermolecular forces holding gases together are significantly weaker than those holding liquids together. This allows the molecules of the gas to move faster than those of a liquid.
In steam are the forces between molecules the same as the forces between the molecules in water?
No, they are not. The forces between molecules in steam are not as strong as those present in liquid water.
Why are gases so easily compressible where as it is a almost impossible to compress a solid or liquid?
There is plenty of space between the molecules of a gas but relatively little between those of a solid or liquid.
What is the term for the movement of molecules within a liquid?
All molecules are in constant motion. Molecules of a liquid have more freedom of movement than those in a solid. Molecules in a gas have the greatest degree of motion. Heat, temperature and the motion of molecules are all related. Temperature is a measure of the average kinetic energy of the molecules in a material. Heat is the energy transferred between materials that have different temperatures. Increasing the temperature increases the translational motion of molecules Energy is related to temperature by the relationship: E= kT

Are particles in a gas or a liquid further apart?
The molecules in a gas are spread further apart than those in a liquid.
In steam are the forces between molecules the same as the forces between the molecules in water?
No, they are not. The forces between molecules in steam are not as strong as those present in liquid water.
Why vapour pressures of solids are far less than those of liquids?
The vapour pressure of solids are far less than those of liquid because solids have fixed arrangement of molecules and between atom of solids their is strong intermolecular forces that held the molecules in place and the molecules of liquid have less intermolecular forces as compared to solids.
Why can the particles in a liquid overcome some forces in attraction?
Particles that make up a liquid move more quickly than those in a solid
Do gas diffuse?
by cooling
Why are gases so easily compressible where as it is a almost impossible to compress a solid or liquid?
There is plenty of space between the molecules of a gas but relatively little between those of a solid or liquid.
What happens to the energy used to evaporate water?
It goes into the molecules of water vapour, which are more energetic than those of liquid water
How does arrangement of atoms in most solids differ from the arrangement of atoms in a liquid?
The arrangement of atoms in solids are different from those in liquids in that they are unable to move from their location in the solid, where they can move in the liquid. A solid's atoms are vibrating very rapidly, but the molecules are all locked into place, whereas in a liquid the molecules are free to move around. Also in general the atoms of a solid are closer together than those of a liquid with the exception of water, whose solid form is less dense.
How are molecules in a particular solid different from the molecules of the substance in a liquid form?
molecules in solids are stationary whilst those in gases and liquids move around, more though in liquid.
Are particles in liquid more spread out than those in a gas?
Take a litre of water and a litre of steam. They are both H20. The heavier one must contain more molecules, and its molecules must be more "closely packed". So, does the liquid or the cas have "particles more spread out"?
