(D) 4 °C
Answer: (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.

A geyser is a hot spring that erupts periodically, shooting a column of hot water and steam into the air. This phenomenon occurs when underground water is heated by magma and builds up pressure until it forces its way to the surface.
