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.

Q1. The speed of light is maximum in Q1. The speed of light is maximum in
(A) Glass (A) Glass
(B) Water (B) Water
(C) Air (C) Air
(D) Vaccum (D) Vaccum
Answer: (D) Vaccum Answer: (D) Vaccum
The speed of light is maximum in a vacuum. Vacuum is the least dense medium with no obstruction to the path of light. Its refractive index is equal to unity, hence, the speed of light is maximum in a vacuum.The speed of light is maximum in a vacuum.
