Question

heat always moves in predictable ways. which of the following is true?
a heat moves from warmer objects to cooler objects until thermal equilibrium is reached.
b heat moves from cooler objects to warmer objects until the warmer objects have greater thermal energy.
c heat moves from larger objects to small objects until thermal equilibrium is reached.
d heat moves from dark - colored objects to light - colored objects until both are cooled.

Explanation:

Heat transfer follows the second law of thermodynamics, where thermal energy naturally flows from regions of higher temperature (warmer objects) to lower temperature (cooler objects). This transfer continues until the temperatures equalize, a state called thermal equilibrium. Options B, C, and D describe incorrect heat transfer patterns: heat does not flow from cooler to warmer spontaneously, nor does it depend on object size or color in the ways described.

Answer:

A. Heat moves from warmer objects to cooler objects until thermal equilibrium is reached.
