Transfer of thermal energy in circulation within fluids is a
A
conduction current.
B
convection current.
C
radiation current.
D
sublimation current.
B
convection current.
The transfer of thermal energy in circulation within fluids is referred to as a B) convection current.
The correct answer is B - convection current.
To understand why, let's break down each option:
A - Conduction current: Conduction refers to the direct transfer of heat through materials that are in physical contact. This process is not applicable to fluids in circulation, as fluids typically flow and mix.
B - Convection current: Convection involves the transfer of heat through the bulk movement of fluid, either in the form of natural convection (caused by density differences) or forced convection (due to external forces like fans or pumps). This is the most appropriate term for the transfer of thermal energy in circulation within fluids.
C - Radiation current: Radiation is the transfer of heat through electromagnetic waves, which can occur without the need for a material medium. While radiation does contribute to heat transfer, it is not specific to the circulation within fluids.
D - Sublimation current: Sublimation refers to the phase change from a solid directly to a gas without passing through the liquid phase. This term does not apply to the transfer of thermal energy in circulation within fluids.
Therefore, the correct answer is B - convection current, as it best describes the transfer of thermal energy in fluids that are circulating.
