Respuesta :

The second law of thermodynamics states that the can never decrease over time.  
The total energy of a system remains constant and it does not change in ideal cases.
From the statements given in the question, the correct answer is the first statement. 

1. the thermal energy is conserved 
First law is Conservation of Energy
Second is that entropy of an isolated system will always increase with time.
Entropy is the change of disorder through time. The best statement which relates to the 2nd law is C. Thermal energy flows from areas of higher to lower temperature
