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.

Option (b) is the correct answer.

Explanation:

Thermal energy is the energy within the particles of an object.

First law of thermodynamics states that for an isolated system energy can neither be created nor it can be destroyed. It can only be transformed from one form to another.

Whereas second law of thermodynamics states that entropy of a system increases with time.

Therefore, when energy of a system increases then there  occurs transfer of heat from hotter to colder substance.

Hence, we can conclude that the statement thermal energy moves from warmer objects to cooler objects.
