Multiple choice Why does a drop of liquid assume a spherical shape? Because a sphere has the least surface area for a given volume. Because a sphere has the largest surface area for a given volume. Because intermolecular forces are strong in liquids. Because intermolecular forces are weak in liquids. Reveal answer Fill a bubble to check yourself A Correct answer Explanation Surface tension causes liquids to minimize their surface area. For a given volume, a sphere has the smallest surface area of any geometric shape.
