How is the temperature of a substance related to attraction between molecules and its states?
Gases have the most kinetic energy and the least attraction exists between its molecules. Liquids have the middle amount of kinetic energy and middle attraction. Solids have the least kinetic energy and most attraction exists between its particles.
The answer above isn't totally accurate, although it is mostly right. However, the attraction between molecules DOES NOT CHANGE WITH TEMPERATURE. What changes is how much energy the atoms/molecules have to overcome that attraction. The higher the temperature, the more energy the molecules have, and therefore the less the attractive force between will actually pull them together.
As an example, consider a space rocket. The force of gravity on the rocket is constant. However, when the rocket is launched, the rocket's engines overcome the attractive force of gravity (by accelerating in the opposite direction) and therefore the rocket takes off. The attractive force doesn't change -- but the rocket's engines are more powerful than that attraction. In the same way, the increased temperature doesn't change the attraction, but it allows the molecules to overcome it.
Other example. Image you are rolling down a hill on a bicycle. In the middle of the downhill, there is a rise. Because you have speed from going downhill, this slight uphill section doesn't stop you. However, the slight uphill is still there! It just doesn't stop you because you are already going fast. But it still affects you.

Difference between adhesion and cohesion?
Adhesion is the intermolecular attraction between 'unlike-molecules' (usually referred to the attraction or joining of two different objects of fluids to each other).Cohesion is the intermolecular attraction between 'like-molecules' (usually referred to the strength with which the particles of an object of fluid attract to each other)
What factors determine the phase of a substance at a given temperature?
It's chemical properties. Each element has a specific boiling point and melting point, as well as freezing point. At room temperature, some elements (water being the most obvious) are liquid at room temperatures. However, some elements are solids (Sodium Chloride, NaCl) or gases (oxygen O2) at room temperature. This all soley depends on the elements specific chemical properties.
What is a relatively weak bond between polar molecules?
A hydrogen bond is a relatively weak bond formed between polar molecules. It occurs between a hydrogen atom bonded to an electronegative atom (such as nitrogen, oxygen, or fluorine) and another electronegative atom in a different molecule.
What is the attraction between substances of the same kind?
The attraction between substances of the same kind is called cohesion. It is due to intermolecular forces such as hydrogen bonding or Van der Waals forces, which cause the molecules to be attracted to each other. Cohesion is responsible for phenomena like surface tension in water.
What is the type of attraction that holds two water molecules together?
The type of attraction that holds two water molecules together is hydrogen bonding. The partially positive hydrogen atom in one water molecule is attracted to the partially negative oxygen atom in another water molecule, creating a strong bond between them.
What is the difference between cohesion and adhesion?
Cohesion is the attraction between molecules of the same substance, while adhesion is the attraction between molecules of different substances.
What is an attraction between molecules of the same substance and why?
An attraction between molecules of the same substance is called cohesion. This occurs because molecules of the same substance have similar properties and are able to bond together through intermolecular forces such as hydrogen bonding or van der Waals forces. Cohesion is responsible for many properties of substances, such as surface tension in water.
What is an attraction between particles of the same substance called?
An attraction between particles of the SAME substance is called cohesion.
What is the difference between cohension and adhesion?
Cohesion is the attraction between molecules of the same substance, leading them to stick together. Adhesion is the attraction between molecules of different substances, causing them to adhere to each other. In simpler terms, cohesion is the attraction between similar molecules, while adhesion is the attraction between different molecules.
The attraction forces between gas molecules lead to?
The attraction forces between gas molecules are very small,but it could be increased by applying high preesure and low temperature. Thus it could be concluded that attraction between gas molecules leads to its liquifaction.
What is the opposite of cohesion?
The opposite of cohesion is adhesion. Cohesion refers to the attraction between molecules of the same substance, while adhesion refers to the attraction between molecules of different substances.
What is a attraction between molecules of the same substance?
This is called an intermolecular force. It may be a van der Waals force, dipole-dipole attraction or a hydrogen bond.
Is water to water an example of whesion or adhesion?
Water to water is an example of cohesion, which refers to the attraction between molecules of the same substance. Adhesion, on the other hand, is the attraction between molecules of different substances.
What is the difference between adhesive and cohesive forces in materials?
Adhesive forces are the attraction between different substances, while cohesive forces are the attraction between molecules of the same substance.
What is the difference between adhesion and cohesion in terms of their properties and behaviors?
Adhesion is the attraction between different substances, while cohesion is the attraction between molecules of the same substance. Adhesion allows substances to stick together, while cohesion allows molecules within a substance to stick together.
How do cohesion and adhesion differ?
Cohesion and adhesion differ because cohesion is an attraction between molecules of the same substance. Adhesion is an attraction between molecules of different substances.Adhesion is the intermolecular attraction between 'unlike-molecules' (usually referred to the attraction or joining of two different objects of fluids to each other).Cohesion is the intermolecular attraction between 'like-molecules' (usually referred to the strength with which the particles of an object of fluid attract to each other).== == == ==
Do in freezing point the molecules of a substance in motion?
the force of attraction between its molecules becomes strong enough to overcome the energy of motion that its molecules have when the substance is in its liquid state, molecules are locked into rigid crystalline formations.
