Which statement correctly relates the first and second laws of thermodynamics? thermal-energy flow between objects is conserved and always flows from the warmer object to the cooler object. thermal-energy flow between objects is conserved and flows from the cooler object to the warmer object. thermal-energy flow between objects is never conserved but flows from the warmer object to the cooler object.

Thermal-energy flow between objects is conserved and always flows from the warmer object to the cooler object.

Here 'conserved' means that the amount of thermal energy lost of by one body is exactly equal to the amount of thermal energy gained by another body, which is the statement of the first law.

According to second law, we do not see objects warming up on their own. For example, if we have a cup of coffee left to itself, we would always see that it cools down. Here, thermal energy is being transferred from warmer object (coffee) to cooler objects (the air in the room).

a.) is the correct answer.
