Not exactly sure what you're asking but I'll give it a shot. Intermolecular forces do not change when a substance undergoes a phase change, such as when something goes from a solid to a liquid. The same intermolecular forces that existed when something was a solid still exist when it changes to a liquid, and vice versa. Its just that with the addition of an external factor (most commonly an increase in temperature) a substance is able to overcome the attractive forces in the solid and break apart into a liquid or when a liquid turns into a gas. For when something freezes or condenses the opposite happens, an external factor (most commonly a decrease in temperature) causes a given substance to be attracted to itself more strongly and then the substances comes together as either a liquid or a solid.

In summary: The forces do not change. Just how much the forces effect the overall substance changes.

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.


Why do real gases deviate from ideal behavior?

Real gases deviate from ideal behavior due to factors such as intermolecular forces, molecular volume, and pressure. These factors cause real gases to occupy more space and have interactions that differ from the assumptions of the ideal gas law.


What role do high vapor pressure and intermolecular forces play in the behavior of a substance?

High vapor pressure and intermolecular forces both influence the behavior of a substance. High vapor pressure indicates that the substance easily evaporates, while strong intermolecular forces suggest that the substance is more likely to stay in a condensed state. These factors affect the substance's physical properties, such as boiling point and phase transitions.


Why do gases deviate from ideal behavior at high pressure?

Gases deviate from ideal behavior at high pressure because the molecules are closer together, leading to stronger intermolecular forces that affect their behavior.


How do intermolecular forces in ethane contribute to its physical properties?

Intermolecular forces in ethane, such as London dispersion forces, affect its physical properties by influencing its boiling point, melting point, and overall stability. These forces are weak compared to covalent bonds but play a significant role in determining the behavior of ethane as a gas at room temperature.

How is a solid and gas the same?

Solids and gases are both states of matter, however they differ in their shape, volume, and intermolecular forces. A solid has a fixed shape and volume with strong intermolecular forces holding the particles closely together, while a gas has no fixed shape or volume and weak intermolecular forces allowing the particles to move freely.


What interaction is not a type of intermolecular force?

Intramolecular forces are not intermolecular forces !


Sulfur dioxide is compartively non ideal at 273K but behaves ideally at 327C.Explain it?

increasing the temperature increases the intermolecular spaces and decreases the intermolecular forces,thus increasing ideality.... so at high temperature of 327c sulphurdioxide is ideal as compared to 273k

What role do dichloromethane intermolecular forces play in determining its physical properties?

Dichloromethane intermolecular forces, such as dipole-dipole interactions and London dispersion forces, influence its physical properties like boiling point, melting point, and solubility. These forces determine how molecules are attracted to each other, affecting the overall behavior of the substance.


What is the intermolecular ammonia and ammonia?

The intermolecular forces are hydrogen bonding.


How do thermal and intermolecular forces behave with each other?

When there is more thermal energy, then there are less intermolecular forces.
