What else can I help you with?
Do strong intermolecular forces have positive numbers?
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.
Are intermolecular forces of attraction strong?
the strength depends on the molecule in question, but they are strong
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.
Is hydrogen bond a biologically weak bond?
Biologically, hydrogen bonds are considered to be strong 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.
Do strong intermolecular forces have positive numbers?
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.

What is a sentence for intermolecular force?
Intermolecular forces shown by the dotted lines not by strong covalent bonds.
What does a strong odor indicate about the strength of intermolecular forces in a compound and why?
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.
Why liquids have a definite volume but no shape?
The intermolecular forces are not sufficiently strong.
What is the correct order of states from least to greatest intermolecular forces of attraction?
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.
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 intermolecular force change from solid to liquid or liquid to gas?
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.
Process of vaporization require an input of energy?
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.
What role does high surface tension play in indicating the strength of intermolecular forces?
High surface tension is indicative of strong intermolecular forces. This is because surface tension is a measure of the cohesive forces between molecules at the surface of a liquid. The stronger the intermolecular forces, the higher the surface tension, as the molecules are more tightly held together.
How melting and boiling points are affected by intermolecular forces?
Melting and boiling points are higher when intermolecular forces (such as hydrogen bonding, dipole-dipole interactions, or London dispersion forces) are stronger. These forces hold molecules together, so more energy is required to overcome them and change the state of the substance. Conversely, weaker intermolecular forces result in lower melting and boiling points.
Is hydrogen bond a biologically weak bond?
Biologically, hydrogen bonds are considered to be strong intermolecular forces.
