Question

Hot water in a container kept on a table transfers heat by which process(es)?

• A. Conduction only
• B. Convection only
• C. Radiation only
• D. Conduction, convection and radiation

Answer 1

The correct option is D Conduction, convection and radiation

There are three modes of heat transfer:
1. Conduction
2. Convection
3. Radiation
In liquids and gases, predominantly heat is transferred by the process of convection but they do transfer heat by the conduction and radiation also.
Hence, hot water transfers heat by the process of conduction, convection and radiation.
