1. Concept:Thermal equilibrium is achieved when two regions in thermal contact cease to have a net exchange of thermal energy, meaning they have reached the exact same temperature.
2. Formula:$$\Delta Q = mc \Delta T$$
3. Solution:- If there is a temperature gradient in an environment, nature seeks balance.
- This balance is achieved through the physical flow of heat from the higher temperature region to the lower temperature region.
- Therefore, it is the fundamental mechanism of 'heat flow' that eventually neutralizes the gradient, resulting in equilibrium.
4. Why other options are incorrect:Heat generation actively disrupts equilibrium. Absorption and dissipation are singular viewpoints of the mechanism; 'heat flow' encompasses the entire interactive transfer process.
Quality & Fidelity Assurance:
Every question on BeambePrep is rigorously curated against the official PMDC syllabus with zero filler, zero out-of-syllabus content, and zero typos. When an authentic past paper originally contained a historical mistake or ambiguity from the examining board (such as UHS or NUMS), BeambePrep faithfully reflects the original paper while detailing the nuance and scientific consensus in the autopsy above.
