Pls answer this question 19 pls

The one direction where energy as heat will be initially transferred between the blocks is from block D to block A.

Explanation:

A substance like metal box that has high temperature will have more kinetic energy between its molecules due to which there will be more number of collisions between them.

Hence, it is able to transfer its heat energy more  readily ac compared to a substance with low heat energy.

As a result, in the given diagram as temperature is increasing from block A to block B so heat energy will be transferred from block D to block A.

Thus, we can conclude that one direction where energy as heat will be initially transferred between the blocks is from block D to block A.

i think it's c. i'm not sure but i think so.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
