What intermolecular forces explain why water is a liquid at room temperature?
Hydrogen bonding is the intermolecular force responsible for water being a liquid at room temperature. The hydrogen bonds between water molecules are relatively strong, allowing them to remain in a liquid state rather than vaporizing at room temperature.
Why is ethanol liquid?
Ethanol is a liquid at room temperature due to its intermolecular forces. The strong hydrogen bonding between ethanol molecules requires more energy to break the bonds, keeping it in a liquid state.
WHAT IS THE INTERMOLECULAR FORCE BETWEEN NF3 IN LIQUID STATE?
Every molecule has a london force (Induce dipole induce dipole force). In this molecule, the intermolecular force that hold these bonds together is dipole-diple interaction or dipolar interaction. There is no hydrogen bonding in here. If there is hydrogen bonding, H-atom must make bond with N,O,F. Therefore, intermolecular forces of NF3 is london force and dipole-diploe
What is the relationship between the strength of intermolecular forces and phase change and density?
Stronger intermolecular forces generally lead to higher melting and boiling points, which are phase changes from solid to liquid and liquid to gas, respectively. Higher intermolecular forces also tend to result in higher densities due to molecules being more tightly packed together in the solid or liquid state.
What are Factors affecting state of a substance?
Factors affecting the state of a substance include temperature, pressure, and the intermolecular forces between the particles of the substance. Changes in these factors can lead to a substance transitioning between solid, liquid, and gas states.
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.
What is the physical state of matter if it has least intermolecular force and greater intermolecular force?
The physical state of matter with the least intermolecular force is a gas, where particles are far apart and move freely. Conversely, the state with the greatest intermolecular force is a solid, where particles are closely packed in a fixed arrangement. Liquids fall in between, with moderate intermolecular forces allowing for both some degree of particle movement and a defined shape.
What is responsible for holding water molecules together in the liquid state?
The main intermolecular force holding water molecules together in hydrogen bonding. Also, there are diplole-dipole interactions and London dispersion forces. But hydrogen bonds are the major force keeping water in the liquid state.
What intermolecular forces explain why water is a liquid at room temperature?
Hydrogen bonding is the intermolecular force responsible for water being a liquid at room temperature. The hydrogen bonds between water molecules are relatively strong, allowing them to remain in a liquid state rather than vaporizing at room temperature.
Does water expand when heated and why?
Yes... When water is heated, the intermolecular force of attraction between water atoms become weak and they start losing the intermolecular force of attraction... at temperature known as boiling point of water this intermolecular force become so weak that water lose its state and converts into gasious state... but this expansion is not considerable... :)
What intermolecular force must be overcome to boil liquid n2?
To boil liquid nitrogen (N2), the intermolecular force that must be overcome is the London dispersion forces. These are weak forces that arise from temporary fluctuations in electron density, leading to temporary dipoles. Although these forces are relatively weak compared to other intermolecular interactions, sufficient energy must be provided (in the form of heat) to break these interactions and transition nitrogen from a liquid to a gaseous state.
Why is ethanol liquid?
Ethanol is a liquid at room temperature due to its intermolecular forces. The strong hydrogen bonding between ethanol molecules requires more energy to break the bonds, keeping it in a liquid state.
What is the predominant intermolecular force in the liquid state of each of NH3?
In the liquid state of ammonia (NH3), the predominant intermolecular force is hydrogen bonding. This occurs due to the presence of a nitrogen atom bonded to hydrogen, where the nitrogen atom is highly electronegative, creating a dipole moment. The hydrogen bonds between NH3 molecules are responsible for its relatively high boiling point compared to similar-sized molecules that only exhibit weaker van der Waals forces. Additionally, dipole-dipole interactions also play a role, but hydrogen bonding is the dominant force.
Do inter-molecular forces occur as a result of being in the liquid state or does a liquid state exist because of inter-molecular forces?
The liquid state is caused by intermolecular forces.

What force has to be overcome in order to change a solid into a liquid?
The force that has to be overcome is the intermolecular forces holding the solid particles in place. As heat is applied, these forces weaken, allowing the particles to move more freely and change from a solid to a liquid state.
