Concept:A good thermometric liquid must not cling to the glass tube so that its level can move freely and give accurate readings.Explanation:Water wets glass because adhesion between water molecules and glass is stronger than cohesion between water molecules.When water is placed in a narrow thermometer tube, it spreads and sticks to the walls.This forms a meniscus, leaves droplets on the glass, and causes inaccurate temperature readings.Although water shows unusual expansion around 0∘C and 4∘C, the correct option is that it wets glass.Answer:D. wets glass.
