Final answer:
The first law of thermodynamics states that energy is conserved, while the second law of thermodynamics states that energy tends to disperse and systems tend to become more disordered.
Step-by-step explanation:
The first law of thermodynamics states that the total amount of energy in the universe is constant. This means that energy cannot be created or destroyed, only transferred or transformed. On the other hand, the second law of thermodynamics states that every energy transfer involves some loss of energy in an unusable form, such as heat energy, resulting in a more disordered system. In other words, no energy transfer is completely efficient and tends toward disorder.
