No, strong intermolecular forces typically have negative values when expressed numerically in terms of energy or potential energy. The more negative the value, the stronger the intermolecular forces.
the strength depends on the molecule in question, but they are strong
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.
Hydrogen bonds are the strongest intermolecular forces because they involve a hydrogen atom bonded to a highly electronegative element (such as oxygen or nitrogen). This creates a large electronegativity difference that leads to a strong attraction between the hydrogen atom and an electronegative atom on another molecule.
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.
A strong odor typically indicates that the compound has weak intermolecular forces. This is because substances with weak intermolecular forces tend to easily vaporize and disperse in the air, allowing their molecules to reach our nose more easily and produce a noticeable smell. Conversely, compounds with strong intermolecular forces tend to have lower vapor pressures and are less likely to produce a strong odor.
No, strong intermolecular forces typically have negative values when expressed numerically in terms of energy or potential energy. The more negative the value, the stronger the intermolecular forces.

Intermolecular forces shown by the dotted lines not by strong covalent bonds.
The intermolecular forces are not sufficiently strong.
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.
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.
The correct order is: gas < liquid < solid. This is because in the gas phase, molecules are far apart and have weak intermolecular forces, in the liquid phase, molecules are closer together with moderate intermolecular forces, and in the solid phase, molecules are tightly packed with strong intermolecular forces.
Hydrogen bonds are the strongest intermolecular forces because they involve a hydrogen atom bonded to a highly electronegative element (such as oxygen or nitrogen). This creates a large electronegativity difference that leads to a strong attraction between the hydrogen atom and an electronegative atom on another molecule.

Yes, the intermolecular forces generally change as a substance transitions from solid to liquid to gas. In solid form, molecules are held together by strong intermolecular forces. In liquid form, these forces weaken to allow molecules to move more freely. In gas form, intermolecular forces are weakest as molecules are far apart and move independently.
Yes, the process of vaporization does require an input of energy. The energy is required to break the intermolecular forces of a given substance. The intermolecular forces is usually very strong.
