How much energy is transferred between a pizza and the oven when both are at a temperature of 80
A
40 J
B
0 J
C
80 J
D
None of the above
Explanation: 

Detailed explanation-1: -In all ovens, heating elements (like coils, or the June Oven’s carbon fiber heating elements) transfer heat energy to a food’s surface via convection and radiation. That heat energy on the food’s surface then spreads, via conduction, towards the food’s center.

Detailed explanation-2: -The quantitative relationship between heat transfer and temperature change contains all three factors: Q = mcT, where Q is the symbol for heat transfer, m is the mass of the substance, and T is the change in temperature. The symbol c stands for specific heat and depends on the material and phase.
