Final answer:
Heat transfer between two substances is primarily influenced by the temperature difference, not volume difference. The rate of heat transfer increases with a larger temperature difference and is also affected by surface area, material conductivity, and thickness.
Step-by-step explanation:
The question revolves around heat transfer rate between two substances with different volumes and temperatures. A key concept in thermodynamics is that heat transfer occurs when there is a temperature difference between two systems. The rate at which heat is transferred is not directly determined by the difference in volume of the two substances, but rather by the temperature difference, represented as T₂ - T₁, where T₂ is the higher temperature and T₁ is the lower temperature.
The rate of heat transfer by conduction is also influenced by factors such as the surface area (A), the material's conductivity (k), and the thickness of the material (d). In a practical scenario, larger temperature differences will result in a greater rate of heat transfer until thermal equilibrium is reached. The material properties and dimensions significantly impact the efficiency and rate of this energy exchange.
