Question

Heat always moves in what direction
from a hot object to a cold object
from a cold object to a hot object
the way it moves always changes

Answer 1

Heat always moves in the direction from a hot object to a cold object. This principle is a fundamental concept in thermodynamics, often stated as the second law of thermodynamics, indicating that thermal energy will spontaneously flow from regions of higher temperature to regions of lower temperature until thermal equilibrium is reached.
