Answer:
Q = 2,341 J (if system is well insulated), 0 J < Q < 2,341 J (if system is not insulated).
Explanation:
This question depends on the fact that system is isolated or not. If the system is well insulated, then, the heat flow is equal to 2,341 J. But if the system is not isolated, a portion of such 2,341 J is transfered to surroundings. Given that air has a low thermal conductivity, heat is transfered mostly to the aluminium block. Then, Q < 2,341 J
