Q1. Water has maximum density at Q1. Water has maximum density at
(A) 100 °C (A) 100 °C
(B) -40 °C (B) -40 °C
(C) 0 °C (C) 0 °C
(D) 4 °C (D) 4 °C
Answer: (D) 4 °C Answer: (D) 4 °C
Water has its maximum density at 4° Celsius (39.2° Fahrenheit), in its liquid phase. At this temperature, water's density is 0.9998395 grams per milliliter (g/ml). This is slightly less than 1 g/ml.
Water behaves abnormally at this temperature. When water is heated from 0° Celsius, its volume decreases until it reaches 4° Celsius. Above 4° Celsius, water's volume increases as the temperature increases. At 4° Celsius, the cage-like structure of water begins to break and come closer, which decreases the volume and increases the density. Water's solid phase, ice, is more buoyant and forms at the surface of bodies of water, where it freezes downward.Water has its maximum density at 4° Celsius (39.2° Fahrenheit), in its liquid phase.
