What happens to energy loss as the temperature difference increases?

When there is a greater temperature difference between two objects or systems, the rate of heat transfer or energy loss tends to increase. This is described by Newton's Law of Cooling, which states that the rate of heat loss of a body is directly proportional to the temperature difference between the body and its surroundings, as long as this difference is not too large.

In practical terms, when two surfaces are at significantly different temperatures, the energy will move more rapidly from the hotter object to the cooler one until thermal equilibrium is reached. Consequently, as the temperature difference widens, the energy lost to the cooler environment also grows, leading to an increase in energy loss. This principle is fundamental in understanding heat transfer processes in thermal physics, where the efficiency of insulation and the design of thermal systems are often evaluated based on temperature gradients.

Given this understanding, the assertion that energy loss increases with an increasing temperature difference is supported both experimentally and theoretically.
