Question

select the correct answer. glenn is heating water in a teakettle. the hotter water at the bottom of the kettle rises. the cooler water near the top sinks and warms. which kind of transfer of heat is this? a. conduction b. convection c. radiation d. transmission

Explanation:

Convection is the transfer of heat by the movement of a fluid (liquid or gas). In the teakettle, the hot water at the bottom rises and the cooler water at the top sinks, creating a circulation pattern typical of convection. Conduction is heat transfer through direct contact, radiation is heat transfer through electromagnetic waves, and transmission is a more general - term not specific to heat transfer in this context.

Answer:

B. convection
