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?
The forces between molecules in steam are weaker than the forces between molecules in liquid water. In steam, molecules are far apart and move freely, resulting in weak intermolecular forces. In liquid water, molecules are closer together and have stronger intermolecular forces due to hydrogen bonding.
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
How are the molecules in a liquid?
How about we look at each of the 3 states (we'll exclude aqueous) and how molecules are bound in each of them. You must understand this though: nomatter what, the molecules will be moving around. However, they bounce off of eachother, almost like the ball in the pinball machine.In a solid, the molecules are extremely compacted, and so when they bounce, there is very little movement going on between them. Think of, in a pinball machine, when the ball gets stuck bouncing over and over between two of the objects. That is like a solid.In a gas, the molecules are freely moving. They have no other molecules hitting them, and that is how they float around so easily.In a liquid, the molecules bounce of eachother, but arent bonded to eachother, and so they each float freely off eachother, though still in the same vicinity, if that makes any sense.

Would a substance of high molecular weight diffuse faster than a substance of lower molecular weight?
No, substances with higher molecular weight typically diffuse more slowly than those with lower molecular weight due to larger size and greater interaction with surrounding molecules. Smaller molecules have less resistance to movement and can diffuse more easily across a membrane or through a solution.
Do gas diffuse?
by cooling
Do molecules at lower temperatures move more quickly than those at higher temperature?
No, molecules at higher temperatures move more quickly than those at lower temperatures. Higher temperatures provide molecules with more kinetic energy, causing them to move faster.
Are particles in a gas or a liquid further apart?
The molecules in a gas are spread further apart than those in a liquid.
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.
Why do molecules at the surface of a liquid behave differently from molecules in the interior of the liquid?
In the interior the intermolecular forces of attraction is equal in all directions but the molecules at the surface of liquid experiences unequal intermolecular forces of attraction. the molecules at the surface are free so the adsorb liquid or gaseous molecules
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.
In steam are the forces between molecules the same as the forces between the molecules in water?
The forces between molecules in steam are weaker than the forces between molecules in liquid water. In steam, molecules are far apart and move freely, resulting in weak intermolecular forces. In liquid water, molecules are closer together and have stronger intermolecular forces due to hydrogen bonding.
When 2 molecules of a solid are kept some distance apart and the force between them is measured solid is then melted to form a liquid. Two molecules are now kept the same distance apart and the force?
The force between the molecules in the liquid state will be weaker compared to the solid state. This is because the intermolecular forces holding the molecules together in a liquid are generally weaker than those in a solid.
How quickly gas spreads in air?
The diffusion rate of gas in air depends on factors like temperature, pressure, and molecular weight of the gas. Gases with lower molecular weight tend to diffuse faster than those with higher molecular weight. In general, gas molecules will spread throughout the air relatively quickly due to their high mobility and ability to mix freely.
Does kinetic energy increase or decrease when a liquid changes to a gas?
Kinetic energy increases when a liquid changes to a gas because the molecules in a gas have higher average kinetic energy compared to those in a liquid. When a liquid evaporates and becomes a gas, the molecules gain more energy and move faster, increasing their kinetic energy.
