Answer:

The direction of any heat transfer between the systems will be from system B to System A.

Explanation:

The direction of any heat transfer between the systems will be from system B to System A.

Even if the system A has a higher thermal Energy it will be from B to A because the system B has a higher temperature than A. The energy will be transferred from B to A until the temperature of the two systems equals and the temperature is in equilibrium.

This comes from the fundamental law of thermodynamics.
