The property of a body to resist change in its state of motion is called
A. Force
B. Weight
C. Momentum
D. Inertia
Answer: Option D
Solution (By JKExamLibrary)
Inertia is directly proportional to mass. Heavier object harder to accelerate/decelerate. Newton's first law defines inertia. Momentum is mass × velocity, depends on motion.
Explanation:
Water's high specific heat (4186 J/kg·K) means it absorbs/releases large heat with small temperature change. This stabilizes temperatures: in engines, water coolant absorbs heat without large ΔT; in organisms, it buffers against temperature fluctuations. Memory tip: 'High specific heat = thermal buffer; water moderates climate and body temperature'. This application question tests understanding of material properties, frequently appearing in competitive exams. Always link physical properties to real-world uses; competitive exams emphasize practical implications of physics concepts.
