Question:- What does the rate of thermal energy transfer depend on?

Answer: The rate of thermal energy transfer depends on several factors, including:

It is expressed as the difference in the temperature of the two objects or substances participating in the thermal energy transfer process. A larger value of Tm1 – Tm2 provides a higher value of heat transfer rate.

The area is exposed to heat that is available for transfer with the surrounding environment. A big surface enables the transfer of heat to occur between the objects or substances that are involved to a greater extent.

The thickness of the said materials and their respective values for thermal conductivity coefficients. Insulators include wood and plastic and they hinder the flow of heat while materials that allow for a fast flow of heat include metals.

The type of heat transfer mechanism at play: Conduction convection or radiation. They all possess different characteristics of heat transfer and some factors, which affect the rate of heat transfer.

Other possible conditions include the architecture of the objects and the formation of insulation or coats; the state of the materials, whether they are in solid, liquid or gaseous state, can as well affect the thermal energy transfer rate in a particular scenario.
