What is the final temperature of A? What is the final temperature of B? These are the equilibrium temperatures of each You have the change above, one of them gets colder, the second gets warmer. The magnitudes of the change is the same, but the direction of these changes is different.

the specfic heat capacity for A and B is 387

$$ C \equiv \frac{ Q}{\Delta T} $$ Since they have the same heat capacity $$ 387=\frac{ Q_A}{\Delta T_A}=\frac{ Q_B}{\Delta T_B}\\ $$ Which means \(Q_B=-Q_B\) Do you agree?
