. Like any equilibrium constant, Kw, changes with temperature. (a) Given that autoionization is endothermic, how does Kw change with rising T? Explain with a reaction that includes heat as a reactant or product. (b) In many medical applications, the value of Kw at 37°C (body T) may be more appropriate than the value at 25°C, 1.0x10-14. The pH of pure at 37°C is 6.80. Calculate Kw, pOH and [OH-] at this T.

Explanation:

The explanation is shown on the second and third uploaded image

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
