d)

Because of its high specific heat, (less-more) energy is required to boil water than is required by many other substances.
a) more
b) less
c)
d)

Water has a (high-low) specific heat, so it can absorb a lot of energy without becoming too warm.

(Cohesion-Adhesion) allows water droplets to stick to other objects, like a spider web.
a) Adhesion
b) Cohesion
c)
