How does temperature change affect water's cohesion?

Answers

The correct answer is the 4th one
Temperature determines the speed of the atoms
It is easy to see that the drop seems to have a "skin" holding it into a sort of flattened sphere (although there is nothing flat about a water drop in outer space.). It turns out that this surface tension is the result of the tendency of water molecules to attract one another. The natural form of a water drop occurs in the "lowest energy state", the state where the atoms in the molecule are using the least amount of energy. For water, this state happens when a water molecule is surrounded on all sides by other water molecules, which creates a sphere or ball (perfectly round if it was in outer space). On Earth, the effect of gravity flattens this ideal sphere into the drop shape we see. Although you may have heard of a "skin" where water meets the air, this is not really an accurate description, as there is nothing other than water in the drop.
Cohesion is basically the attraction between molecules within a substance. I the case of water, the cohesion will definitely decrease with the increase in temperature. With the increase in temperature, the molecules will start vibrating more and the attraction among them will decrease. I hope the answer helps you.
Cohesion is attraction between molecules in a substance. When the temperature increases the particles will begin the vibrate more and the attraction between them will decrease. 
Addition of sugar will increase the viscosity of water.  The adhesive force between the tube and liquid molecules determine the rate of capillary action. When salt is added to water, its freezing point decreases.  When temperature increases ,cohesion of water decreases.  When temperature increases surface tension decreases.  

Explanation:

Viscosity is the resistance to flow offered by liquids. Addition of sugar makes water sticky and increases viscosity. Salt addition lowers the freezing point of water. Thus salt can help the melting process of ice.  

Cohesion is the force of attraction between the molecules of same type. The cohesion of water decreases with the increase in temperature and molecules become more  free. Surface tension is contributed by the cohesive force fluid molecules.  

This indicates that surface tension decreases with temperature increase since cohesion also decreases.  

makes it way colder

The cohesive forces between the water molecules will decrease.

Explanation:

Cohesive forces are defined as the molecular forces which are present between same substances.

Cohesive forces between the water molecules means the forces which are present between water molecules.

Thus, if the temperature of the system increases, water particles move apart because they gain kinetic energy. The forces binding water molecules together will weaken up and so, the cohesive forces between the water molecules will decrease.

Higher temp causes H bonds to break
Lower causes them to stabilize

Adhesive and cohesive properties are based on h bonds
