Heat always moves from:

• A. an object at lower temperature to an object at higher temperature
• B. an object with lower energy to an object with higher energy
• C. an object at higher temperature to an object at lower temperature
• D. an object with less mass to an object with more mass

Answer: (C)

Verified step by step guidance

1. Understand the concept of heat transfer: Heat is the energy that flows between two objects due to a temperature difference.
2. Recall the Second Law of Thermodynamics, which states that heat naturally flows from a region of higher temperature to a region of lower temperature until thermal equilibrium is reached.
3. Recognize that temperature is a measure of the average kinetic energy of particles in a substance, so heat moves from the object with higher temperature (higher average kinetic energy) to the object with lower temperature (lower average kinetic energy).
4. Note that heat transfer is not directly dependent on the total energy or mass of the objects, but rather on the temperature difference between them.
5. Conclude that the correct statement is: Heat always moves from an object at higher temperature to an object at lower temperature.
