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

Answer 1

the correct answer is B

Answer 2

Answer: Option (b) is the correct answer.

Step-by-step explanation:

The energy present within the molecules of an object is known as thermal energy.

When an object is warmed then its molecules gain more kinetic energy and results in more number of collisions. Then they release extra energy in the form of heat into the atmosphere.

And when a cool object is placed adjacent to a warmer object then heat transfers from warm object to cool object.

Thus, we can conclude that thermal energy moves from warmer objects to cooler objects.
