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 dierdras 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:

Step1: Recall thermodynamics laws

The first law of thermodynamics is about energy conservation in a system. The second - law states that heat (thermal energy) naturally flows from a region of higher temperature (warmer object) to a region of lower temperature (cooler object).

Step2: Analyze options

Option A is against the natural heat - flow principle. Options C and D violate the first law of thermodynamics which states that energy cannot be created or destroyed in an isolated system. So the correct statement is that thermal energy moves from warmer objects to cooler objects.

Answer:

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