Why do intermolecular forces exist between water molecules?
Intermolecular forces exist between water molecules due to the presence of polar covalent bonds within the water molecule, created by the unequal sharing of electrons between oxygen and hydrogen atoms. This polarity allows water molecules to attract each other through dipole-dipole interactions, as the positive and negative ends of different water molecules are attracted to each other. This results in hydrogen bonding, a specific type of intermolecular force that is particularly strong in water.
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 water boils intermolecular forces are overcome?
Yes, when water reaches its boiling point, the intermolecular forces holding the water molecules together are overcome, allowing the molecules to escape as steam. This is a physical change as the water changes from a liquid to a gas.
Does CH3CH2OH and H2O contain similar intermolecular forces?
When CH3CH2OH and H2O are mixed together to form a homogenous solution, CH3CH2OH forms additional hydrogen bonding with water molecules.
What can you say about the relative strength of the intermolecular forces in the two compounds?
The relative strength of intermolecular forces depends on the types of molecules involved. Compounds with hydrogen bonding, such as water, tend to have stronger intermolecular forces compared to those with only London dispersion forces, like diethyl ether. This results in higher boiling points for compounds with stronger intermolecular forces.

How do intermolecular forces determine a substance's state?
If the intermolecular forces are great enough they can hold the molecules together as a liquid. If they are even stronger they will hold the molecules together as a solid. Water has nearly the same mass as methane and ammonia molecules, but the greater molecular forces between water molecules causes the water to be liquid at room temperature, while ammonia and methane, with weaker intermolecular forces, are gases at room temperature.
what are liquids mobile?
Liquids are mobile because the intermolecular forces between their molecules are weak enough to allow the molecules to move around relative to one another. These intermolecular forces are the forces of attraction between the molecules, and they are what hold the molecules together in a liquid. However, the intermolecular forces in liquids are not as strong as the intermolecular forces in solids, so the molecules in a liquid are able to move around more easily. This is why liquids can flow and take the shape of their container. The strength of the intermolecular forces in a liquid depends on the type of liquid. For example, water has strong intermolecular forces because the molecules of water are polar, meaning that they have a positive end and a negative end. This polarity allows the water molecules to form hydrogen bonds with each other, which are very strong intermolecular forces. As a result, water is a very mobile liquid, but it is not as mobile as a gas, such as air. The mobility of a liquid can also be affected by temperature. As the temperature of a liquid increases, the molecules of the liquid move faster and the intermolecular forces become weaker. This is why liquids become more mobile as they heat up. For example, water at room temperature is a liquid, but it becomes a gas when it is heated to 100 degrees Celsius.visit- In conclusion, liquids are mobile because the intermolecular forces between their molecules are weak enough to allow the molecules to move around relative to one another. The strength of the intermolecular forces in a liquid depends on the type of liquid and the temperature of the liquid.
Are the melting point of water the dispersion of molecules?
Melting involve that intermolecular forces are weakened.
What causes of the water to evaporate?
The intermolecular forces between water molecules are lowered at the water surface and some molecules escape in the atmosphere. Evaporation is increased by temperature.
Explain why oil does not dissolve in water.?
The main intermolecular forces between water molecules are hydrogen bonds which are pretty strong as far as intermolecular forces go. Between hydrocarbon chains (oil) the main intermolecular force are London force which are weaker. For two liquids to be miscible the intermolecular forces between them have to be similar in strength or they won't dissolve. Water and oil have different strengths of intermolecular bonds so don't mix.
Does CH3CH2OH and H2O contain similar intermolecular forces?
When CH3CH2OH and H2O are mixed together to form a homogenous solution, CH3CH2OH forms additional hydrogen bonding with water molecules.
Does The meniscus in a test tube of water demonstrates the equal effect intermolecular forces have on all particles in a liquid?
Yes, the meniscus in a test tube of water demonstrates the equal effect intermolecular forces have on all particles in a liquid. The meniscus forms due to the cohesion between water molecules and adhesion with the test tube, which is a result of intermolecular forces acting uniformly on all water molecules at the surface.
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 is the most important type of intermolecular forces between molecules in a sample of pure water?
Hydrogen bonding
