Is slices of tender meat grilled under an electric grill a conduction?

Yes, grilling tender meat under an electric grill is primarily an example of conduction. Here's why:

* Conduction: Heat transfer through direct contact. The hot electric grill element directly touches the meat, transferring heat through the metal surface.

* How it works: The electric grill's heating element gets hot, and this heat is then transferred to the metal grilling surface. The meat, when placed on the hot surface, absorbs this heat through direct contact. This is why you see those lovely grill marks!

Other forms of heat transfer might be present but are less significant:

* Radiation: Some heat might be radiated from the element to the meat, but this is generally less than conduction.

* Convection: There might be a small amount of air convection happening around the meat, but it's not the primary method of heat transfer.

In summary: The dominant way the meat is cooked in this scenario is through conduction, where heat is directly transferred from the hot grilling surface to the meat.
