Part a what happens to these physical properties as the strength of intermolecular forces increases? drag each item to the appropriate bin. hints melting pointvapor pressureboiling pointviscositysurface tension increase decrease

1. Melting point is the temperature at which the solid turns to liquid. In order to reach this point, the intermolecular forces of the solid must be broken so that it would incorporate the molecular arrangement of a liquid. So, the stronger the intermolecular forces, the greater the energy which consequently leads to higher melting points.

2. Vapor pressure is the pressure exerted by the gas above its solid or liquid substance. It is closely related to volatility, which is the ability of the substance to convert from liquid to gas at a certain temperature. The stronger the intermolecular force, the less volatile the substance is which is manifested in increasing vapor pressure.

3. Boiling point has the same concept as melting point, but the change is from liquid to gas. So, the stronger the intermolecular forces, the greater the energy which consequently leads to higher boiling points.

4. Viscosity is the ease of fluidity. Solids, which have stronger intermolecular forces are not viscous at all. So, the stronger the intermolecular forces, the viscosity decreases.

5. Surface tension is the force the substance exerts near its surface or interface. The stronger the intermolecular force, the stronger the surface tension.
