Question

dierdra began writing a summary of the relationship between the first and second laws of thermodynamics. thermal energy in a system is conserved and can increase the system’s internal energy and/or be used to do work. which best completes dierdra’s summary? thermal energy moves from cooler objects to warmer objects thermal energy moves from warmer objects to cooler objects. thermal energy is destroyed when it leaves the system. thermal energy is created when it enters the system.

Explanation:

The second - law of thermodynamics states that heat (thermal energy) naturally flows from a region of higher temperature (warmer object) to a region of lower temperature (cooler object). The first law states that energy is conserved. Thermal energy is not created or destroyed (violating conservation in options C and D), and it doesn't flow from cooler to warmer spontaneously (violating the second - law in option A).

Answer:

B. Thermal energy moves from warmer objects to cooler objects.
