64. The boiling point of liquids vary as A.Pressure varies B.Temperature varies C.Volume varies D.Density varies
Option A Solution: The boiling point of a liquid varies according to the applied pressure; the normal boiling point is the temperature at which the vapour pressure is equal to the standard sea-level atmospheric pressure (760 mm [29.92 inches] of mercury). At sea level, water boils at 100°C (212°F).
