A hot piece of iron is placed into a container of water. Describe two ways in which heat is transferred in this system.

zarkam21 · Answer

Radiation and convection

zarkam21 · Answer

radiation because of the electromagnetic waves

Vocaloid · Answer

I'm not sure about radiation, where would it be coming from

zarkam21 · Answer

convection because it is going through a solid object

Vocaloid · Answer

going through a solid object would be conduction, convection is for heat transfer through fluids

zarkam21 · Answer

Convection, because the heat from the hot iron is transfered through water (fluids)

Vocaloid · Answer

good, so conduction + convection
