2nd opinion: thermal equilibrium
It\'s still called heat.

The energy that flows between objects with different temperatures is called heat. Heat will naturally transfer from a warmer object to a cooler object until thermal equilibrium is reached.
when heat flows Out of a system
The energy that flows between objects with different temperatures is called heat. Heat transfer occurs from a region of higher temperature to a region of lower temperature in order to reach thermal equilibrium.
Heat is energy and cannot be negative, If you are talking about heat flow then if you define outflow to be negative then inflow is positive.

heat flows from a warmer object to a cooler object.
Yes, energy that flows between objects with different temperatures is called heat. Heat transfer occurs through three main mechanisms: conduction, convection, and radiation. Heat always flows from areas of higher temperature to areas of lower temperature in an attempt to reach thermal equilibrium.
