Heat will flow from a hot object to a cold object until the objects reach stability. collapse. equilibrium. boiling point.

equilibrium

Explanation:-

Equilibrium is a condition in which the state of a body or physical system that is at rest or in constant and unchanging motion. Heat flow occurs from a hot body to a cold body until both the bodies attain the same temperature and after that no heat flow occurs in any direction and thus the system is said to have attained equilibrium.

Collapse is defined as the process in which there is a sudden fall because of pressure or having no strength or support.

Boiling point is the temperature at which vapor pressure becomes equal to the atmospheric pressure.
