The attraction between substances of the same kind is called cohesive attraction or cohesive force. It is the property of similar molecules to stick together.

What is a relatively weak bond between polar molecules?
A polar molecule is positive on one end and negative on the opposite end. A hydrogen bond is a special attraction between polar molecules, a weak bond.
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.
What is the simplest substances in nature composed of the same atoms?
Hydrogen gas
How does cohesion affect living organisms?
Cohesion is the attraction or holding together of molecules of the same substance. It affects living organisms through water, which also has adhesion (holding together of molecules of different substances). A combination of cohesion and adhesion creates capillary action, the ability for water (or any liquid) to run along a surface. (basically, it allows water to climb up small tubes.
Why do most animals have the same kinds of organ systems?
Many animals derived from one ancestor I believe it is because most animals are the relatively the same if we are assuming that all animals evolved from the same previous life form. Most animals need the same nutrients and are composed of CHNOPS (Carbon, Hydrogen, Nitrogen, Oxygen, Phosphorus, and Sulfur). The molecules of life are carbohydrates, lipids, proteins, and nucleic acids which perform the functions needed for living things to survive. This answer is kind of confusing, but... a shortened version is: Animals are composed of mostly the same substances, and the substances all need the same thing. To get the same nutrients, they have created organs to perform the functions needed to get these nutrients. *Don't quote me on this though. This is my opinion and I have nothing to back me up currently*
What is a attraction between molecules of different substances?
Adhesive forces are the attraction between molecules of different substances. This differs from cohesive forces which is attraction between same substances.
The attraction among molecules of different substances is called?
An attraction between substances of the same kind is called cohesion. However, if it occurs in water, then it is known as capillary action.
Compare contrast the terms adhesion and cohesion?
Cohesion- Is An Attraction Between Molecules Of The Same Substance.Adhesion- Is An Attraction Between Molecules Of Different Substances.
What is the force of attraction between particles of the same kind?
Gravity. Gravity affects all things, same kind or not.
What is an easy way to remember adhesive and cohesive?
Adhesion is the attraction bettween molecules of different substances. Cohesion is the attaction between moleculesof the same substances.
Whats the difference between adhesion and cohesion?
Adhesion is the attraction between two molecules of different substances.cohesion is the attraction between molecules of the same substances.
What is the definition of cohesion force?
Cohesive force is the force of attraction between molecules of the same kind or of the same substance. Eg. cohesive force of attraction exists between water molecules
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 attraction between the same kind of molecules?
adhesion is the attraction which allows molecules of different kinds of matter to stick together!
In water can you say the attraction between H2 and Ois Adhesion and H2O and H2O is Cohesion?
No, in water, the attraction between H2 and O is a covalent bond that forms the water molecule. Adhesion refers to the attraction between different molecules, while cohesion refers to the attraction between the same molecules. In water, the attraction between H2O molecules is cohesion, and the attraction between water molecules and other substances is adhesion.
What is a relatively weak bond between polar molecules?
A polar molecule is positive on one end and negative on the opposite end. A hydrogen bond is a special attraction between polar molecules, a weak bond.
What is attracted between molecules of the same substances?
This is called an intermolecular force. It may be a van der Waals force, dipole-dipole attraction or a hydrogen bond.
