Which of the following statements about state functions is true? a)The state functions associated with the ideal gas law are P, V, T, and R
b)State functions are path dependent
c)State functions describe quantitative values of a system at equilibrium
d)As a system undergoes changes, the value of a state function must increase

- lead + phosphoric acid = hydrogen + lead(ii) phosphate

the answer would be c

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.

hope this .
