Water has maximum density at || ADRE 1.0 SLRC 2022 PAPER-III SOLVED QUESTIONS

Water has maximum density at

(A) 100 ºC

(B) –40 ºC

(C) 0 ºC

(D) 4 ºC


Answer: D) 4 ºC


Explanation:

Water reaches its maximum density at 4 degrees Celsius. This unique property of water is due to the hydrogen bonding between water molecules, which causes the molecules to be most closely packed at this temperature. As water cools below 4 ºC, it begins to expand, which is why ice is less dense than liquid water and floats.

This question was previously asked in ADRE's SLRC-2022 Paper-III, highlighting its importance for candidates preparing for competitive exams. It assesses knowledge of basic scientific principles and the properties of water, which are fundamental topics in general science.


Why this question is important

Understanding the physical properties of water is crucial for various scientific and general knowledge sections in competitive exams like ADRE. This knowledge is fundamental for roles requiring a basic understanding of scientific concepts.
