How is elasticity related to intermolecular forces?

Elasticity is a property of matter due to which it regains its original configuration when deforming force is removed. The force which is responsible to hold together the atoms or molecules of a matter is called intermolecular force.

How do intermolecular forces affect matter?

Intermolecular forces are the forces that bind two molecules together. Physical properties are affected by the strength of intermolecular forces. Melting, boiling, and freezing points increase as intermolecular forces increase. Vapor pressure decreases as intermolecular forces increase.

Does intramolecular forces affect viscosity?

Intermolecular forces present in a liquid is a factor which affects its viscosity. Higher the intermolecular forces, higher will be the viscosity. When there is a strong intermolecular force, the molecules of the liquids are strongly bonded to each other. This induces a resistance to move.

What is the role of intermolecular forces and intramolecular forces in surface tension?

Stronger intermolecular forces will produce greater surface tension . The intermolecular forces present in a sample of water are hydrogen bonds . If the hydrogen bonds are removed or disrupted, the surface tension will decrease.

What do forces between molecules in an elastic object cause?

This force is called elastic force. The farther the material is stretched or compressed, the greater the elastic force becomes. As soon as the stretching or compressing force is released, elastic force causes the material to spring back to its original shape.

Which force is responsible for the property of elasticity of a body?

The elasticity of materials is described by a stress–strain curve, which shows the relation between stress (the average restorative internal force per unit area) and strain (the relative deformation).

How do intermolecular forces affect volatility?

Substances with strong intermolecular forces have lower vapor pressures and are less volatile, while substances with weak intermolecular forces have higher vapor pressures and are more volatile.

How does cohesive force affect viscosity?

Due to strong cohesive forces between the molecules, any layer in a moving fluid tries to drag the adjacent layer to move with an equal speed and thus produces the effect of viscosity as discussed earlier. Since cohesion decreases with temperature, the liquid viscosity does likewise.

How do intermolecular forces affect the surface tension and viscosity as intermolecular forces increase what happens to each property?

As the intermolecular attraction increases, • The vapor pressure ( the pressure of the vapor that is in equilibrium with its liquid) decreases • The boiling point ( the temperature at which the vapor pressure becomes equal to the pressure exerted on the surface of the liquid) increases • Surface tension ( the …

How does intermolecular forces affect capillary action?

Capillary Action. Intermolecular forces also cause a phenomenon called capillary action, which is the tendency of a polar liquid to rise against gravity into a small-diameter tube (a capillary), as shown in Figure 11.4. 3. When a glass capillary is is placed in liquid water, water rises up into the capillary.
