What type of energy transfer takes place in the absence of any solid or fluid as a transfer medium? a. conduction b. convection c. radiation d. contusion
Answers
C. radiation
Explanation:
A Conduction is a type if energy transfer that takes place through a solid medium called a conductor so A Conduction is wrong
B Convection is a type Of energy transfer that takes place in fluids. ( that is a liquid or gas ) As more energy is released into their particles the particles closer to the heat become lighter and rise while the denser ones fall to receive energy and become light, this process continues until the fluid is completely heated hence B Convection is wrong
D Contusion this option is just put as a confusion as a contusion is merely just a wound or bruise on the surface of a thing hence D Contusion is wrong
C Radiation. This is a type of energy Transfer that requires no medium for transfer it permits the transfer of heat to different area via wave like heat waves from the sun that passes through the vacuum of space ( no material medium makes up a vacuum ) to warm us up hence C Radiation is Correct
why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
