Heat always move from a ______ object to a ______ object. Which word correctly complete this sentence?*1 pointcold / warmbig / smallwarm / coldsmall / big

The correct answer is: warm / cold.

Explanation:

Heat transfer occurs due to a difference in temperature between two objects. According to the second law of thermodynamics, thermal energy will naturally flow from a warmer object to a cooler one until thermal equilibrium is reached, meaning their temperatures equalize. This principle is fundamental in various physical processes, including conduction, convection, and radiation.

For example, when you place a warm cup of coffee on a cold countertop, heat moves from the coffee (the warm object) to the countertop (the cold object). This concept is crucial in understanding thermodynamics and energy transfer, and it underpins many everyday phenomena. Thus, the completion of the sentence with "warm" for the first blank and "cold" for the second accurately describes the natural direction of heat flow.
