Sample Answer: "Heat transfer is the process of thermal energy exchange between objects with different temperatures. Conduction involves heat transfer through direct contact between solids, where energy is transferred from high-energy particles to low-energy particles. Convection involves the transfer of heat through the movement of fluids, either natural (due to density differences) or forced (by mechanical means). Radiation is the transfer of heat through electromagnetic waves, such as the heat we receive from the sun."

How to Answer: Define stress and strain in the context of mechanics. Explain the relationship between stress and strain using the elastic modulus (Young's modulus) and Hooke's law.

Sample Answer: "Stress is the internal resistance experienced by a material when subjected to an external force or load. Strain, on the other hand, is the measure of deformation resulting from the applied stress. These two are related through the material's elastic modulus, which represents its stiffness. Hooke's law further establishes the linear relationship between stress and strain within the elastic limit of a material."
