21.   The surface tension of a liquid is the minimum force needed to overcome this inward pull and thus expand the surface area.

22.   Rectal CSA values related to height, weight, and surface area showed no significant relation.

23.   They reported large and significant reductions in surface area affected and severity of signs and symptoms of atopic eczema.

24.   Goldgar et al have shown that total naevus density, or percentage of body surface area covered by naevi, is a measure that correlates well with melanoma risk.

25.   The surface area of a plate is reduced at a subduction zone whereas it is increased along a spreading ridge.

26.   For instance, a rock shattered through physical weathering will be more liable to chemical weathering because of the increased surface area made available for chemical reactions.

27.   A fine-grained, permeable rock, for instance, will provide a much greater surface area than a densely cemented, massive rock.

28.   The surface area of any sphere is proportional to the radius squared.

29.   Any tendency to increase the ratio of surface area to weight would help, for example flaps of skin growing out in the angles of joints.

30.   And in flight, the long warhead was instructed to fly sideways, exposing a greater surface area to the distant heat seeker.
