Two parallel plates separated by 150 mm are kept at temperatures of 1000°C and 70°C respectively. Which mode of heat transfer predominantly occurs between them?

Multiple choice question for Heat Transfer. Select an option, then review the explanation below.

Choose the correct answer

Explanation

Given the large temperature difference and the gap between the plates, heat transfer primarily occurs through thermal radiation rather than convection. While convection may contribute, radiation is the dominant mode in this scenario.
