What is the same and different between the spacing in molecules in solid and a gas?
In a solid, molecules are closely packed together with strong intermolecular forces, leading to a fixed shape and volume. In a gas, molecules are far apart with weak intermolecular forces, allowing them to move freely and fill the container they are in. Both phases have molecules, but differ in their spacing and behavior due to their respective intermolecular forces.
When a liquid is heated how does its volume change?
When a liquid is heated, its volume generally expands and increases, causing the molecules to move further apart. This expansion is due to the increase in the kinetic energy of the molecules, which leads to weaker intermolecular forces and greater separation between the molecules.
What changes if the degree (amount) of intermolecular bonds of a substance are changed?
Changing the degree of intermolecular bonds in a substance can affect its physical properties such as melting point, boiling point, and viscosity. Increasing the number of intermolecular bonds can lead to stronger forces between molecules, making it harder to separate them, while decreasing the number of intermolecular bonds can weaken the forces between molecules, leading to easier separation.
How do molecules act in a solid?
In a solid, molecules are tightly packed and held in a fixed position by strong intermolecular forces. These forces prevent the molecules from moving freely past one another, giving solids their definite shape and volume. The molecules only vibrate in place, leading to the solid's rigidity.
Which descritpion best fits a solid?
definite volume; shape of container; moderate intermolecular attractionsdefinite volume; shape of container; no intermolecular attractionsvolume and shape of container; no intermolecular attractionsdefinite shape and volume; strong intermolecular attractionsvolume and shape of container; strong intermolecular attractions
Why a liquid have a volume?
Because it's molecules are still under strong intermolecular forces,so they are not easily compressible.

Explain what is the difference between real gas molecules and ideal gas molecules by kinetic theory?
Real gas molecules have volume and experience intermolecular forces, while ideal gas molecules are treated as point particles with negligible volume and no intermolecular forces. In real gases, molecules have varying speeds and collision effects due to their volume and interactions, while ideal gases follow the assumptions of the kinetic theory perfectly due to their simplified behavior.
How are the molecules in a particular solid different from the molecules of that substance in a liquid form?
the molecules in solids are tigthly packed that is the intermolecular force(cohesive) force is more but in liquids the intermolecular force(cohesive force) is less .solids have fixed shape,volume, mass but liquids have no fixed shape as it takes shape of the container.
Why molecular volume is used istead of molar volum in parachor?
Molecular volume is used in parachor calculations because it considers the actual space occupied by the molecules themselves, taking into account their shape and size. This is important for predicting intermolecular interactions. Molar volume, on the other hand, is a bulk property that does not provide the same level of detail for such calculations.
When a liquid is heated how does its volume change?
When a liquid is heated, its volume generally expands and increases, causing the molecules to move further apart. This expansion is due to the increase in the kinetic energy of the molecules, which leads to weaker intermolecular forces and greater separation between the molecules.
What is the molecules of an ideal gas?
The molecules of an ideal gas have negligible volume and no intermolecular forces acting between them. They are in constant, random motion and collide elastically with each other and the walls of the container. The behavior of an ideal gas is described by the ideal gas law, PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.
Why do solids have fixed shape and gases have niether a fixed shape nor a fixed volume?
The intermolecular forces between gas molecules are extremely weak.
Why real gases deaviat from ideal behaviou?
It is assumed that Ideal Gases have negligible intermolecular forces and that the molecules' actualphysical volume is negligible. Real Gases have the molecules closer together so that intermolecular forces and molecules' physical volumes are no longer negligible. High pressures and low temperatures tend to produce deviation from Ideal Gas Law and Ideal Gas behavior.
What changes if the degree (amount) of intermolecular bonds of a substance are changed?
Changing the degree of intermolecular bonds in a substance can affect its physical properties such as melting point, boiling point, and viscosity. Increasing the number of intermolecular bonds can lead to stronger forces between molecules, making it harder to separate them, while decreasing the number of intermolecular bonds can weaken the forces between molecules, leading to easier separation.
Does a gas have more moleules than a liquid?
No. The state of a substance does not tell the number of molecules present. In a gas, the molecules move more freely than in a liquid as they are not bound to each other by intermolecular forces. If you're going by volume, a given volume of a gas will generally contain fewer molecules except at very high pressures.
A real gas differs from an ideal gas because the molecules of real gas have?
higher molecular volumes and exhibit intermolecular forces, such as van der Waals forces, that cause deviations from ideal gas behavior. These intermolecular forces affect the compressibility, volume, and pressure of a real gas, making it different from the assumptions of an ideal gas.
