Ravi's performance was on the same lines. For Ching Man the same observation as before was
made. That is, the abstract pictures seemed to guide him in what he identified in his explanations.
When the pictures showed a "before" and an "after" instance, he also accounted for both instances
in his explanations, whereas when the pictures showed only the "before" instances he limited his
accounts to identifying the temperature differences and the energy flows when they existed; he thus
did not identify the temperature changes incurred by the energy flows, nor did he mention that the
temperatures of the system and its surroundings end up the same at equilibrium.
