Water's high specific heat useful for: MCQ with Answer and Explanation

Water's high specific heat useful for:
A. Biological temperature regulation
B. Engine cooling
C. Neither
D. Both
Answer: Option D
Solution (By JKSSB Mock Tests)
High c = absorbs/releases large heat with small ΔT. Stabilizes engine temperatures and organism body temperatures. Memory tip: 'High specific heat = thermal buffer; water moderates climate and physiology'. Property application frequently tested in competitive exams.

Question #2
A wire of resistance 6 Ω is stretched to thrice its original length. New resistance is
A. 54 Ω
B. 18 Ω
C. 2 Ω
D. 36 Ω

Correct Answer: Option A


Explanation:
R ∝ L² (volume constant). L'=3L => R' = 3² × 6 = 9×6 = 54 Ω. Generally, R' = n² R for stretching n times. Important concept.
