Question

which explains why conduction is unlikely when ice is placed on a freezer shelf?
there is no direct contact.
the ice is too cold.
the shelf acts as an insulator.
the ice and shelf are the same temperature.

Explanation:

Conduction is the transfer of heat through direct contact between materials. For conduction to occur, there must be a temperature difference between the two objects in contact. If the ice and the freezer shelf are at the same temperature, there is no driving force for heat transfer via conduction.

• Option 1: Ice is placed on the shelf, so there is direct contact.
• Option 2: Coldness alone (without a temperature gradient) does not prevent conduction.
• Option 3: Freezer shelves are not typically insulators in this context.

Answer:

The ice and shelf are the same temperature.
