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.

A relative clause is a dependent clause that begins with a relative pronoun (such as who, which, that, or whom) and provides additional information about a noun in the main clause.A relative clause is a dependent clause that begins with a relative pronoun (such as who, which, that, or whom) and provides additional information about a noun in the main clause.
Q4. The speed of light is maximum in Q4. 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.

Q9. What is the term for the movement of water through a plant, from the roots to the leaves, and is then released into the air as water vapor? Q9. What is the term for the movement of water through a plant, from the roots to the leaves, and is then released into the air as water vapor?
Transpiration is the process by which plants transport water and minerals from the roots to the leaves, where it is used for photosynthesis and other metabolic processes. Excess water is released into the air as water vapor through tiny openings called stomata.Transpiration is the process by which plants transport water and minerals from the roots to the leaves, where it is used for photosynthesis and other metabolic processes.
