Question

which best describes the direction of heat? from a substance with no thermal energy to a substance with high amounts of thermal energy from a substance with less thermal energy to a substance with more thermal energy from a cooler substance to a warmer substance from a warmer substance to a cooler substance

Explanation:

Heat naturally flows from a region of higher temperature (warmer substance) to a region of lower temperature (cooler substance) due to the second - law of thermodynamics which states that in spontaneous processes, entropy of an isolated system increases. Temperature is a measure of the average kinetic energy of the particles in a substance, and heat transfer occurs to equalize the temperatures.

Answer:

from a warmer substance to a cooler substance
