Question 25 • (AG Q3) Science 8: 25-26 (ELux)

Which explains why conduction is unlikely when ice is placed on a freezer shelf?

Answer
A
There is no direct contact.
B
The ice is too cold.
C
The shelf acts as an insulator.
D
The ice and shelf are the same temperature.

Explanation

Conduction transfers thermal energy through direct contact when there is a temperature difference. Ice placed in a freezer is usually at about the same temperature as the shelf, so little or no heat flows between them by conduction. The best choice is “The ice and shelf are the same temperature.”
