WebWhich statement describes how heat is transferred by convection? Air molecules touch the warm ground, heating them up. Sunlight travels through space without the aid of fluids or solids. Warm air rises and takes heat with it; eventually it cools and sinks. Land and ocean absorb and re-emit heat from the sun. Web30 jan. 2024 · Although often discussed as a distinct method of heat transfer, convective heat transfer involves the combined processes of conduction and advection. According to the question, the correct option is A that is Warm air rises and takes heat with it; eventually, it cools and sinks. Hence, the option is A. For more information, refer to the link:-
Web5 nov. 2024 · Heat is used to raise the temperature of air so that Q = m c Δ T. The rate of heat transfer is then Q t, where t is the time for air turnover. We are given that Δ T is 10.0ºC, but we must still find values for the mass of air and …
