6. Define transfer of heat?
Answers
Explanation:
Heat transfer is a discipline of thermal engineering that concerns the generation, use, conversion, and exchange of thermal energy between physical systems. Heat transfer is classified into various mechanisms, such as thermal conduction, thermal convection, thermal radiation, and transfer of energy by phase changes. Wikipedi

The theory of heat transfer seeks to predict the energy transfer that may take place between material bodies as a result of temperature difference. This energy transfer is defined as heat. The three modes by which heat can be transferred from one place to another are conduction, convection and radiation.
When a fluid, such as air or a liquid, is heated and then travels away from the source, it carries the thermal energy along. This type of heat transfer is called convection. The fluid above a hot surface expands, becomes less dense, and rises.
Answer:
To carry heat from one part of an object to its other part, or from one object to another object is called transfer of heat. For example: If we dip a steel spoon in a cup of hot tea, we find that the temperature of spoon rises and it becomes hot.
