Question

The second law of thermodynamics states that __________.
a) the total energy in the universe is increasing with time
b) all of the food energy eaten by an organism can be used by that organism
c) in any transformation, some of the original energy is converted to heat or light and the system becomes more disordered
d) the energy in the universe is constant

Answer 1

Answer: Option (c) is the correct answer.

Explanation:

According to the second law of thermodynamics, there will always be increase in entropy of the Universe.

And, entropy is the degree of randomness or disorderness. This means that more is the movement of particles of a system more will be the entropy of system.

During this process, some of the energy is lost in the form of heat or light due to which the system becomes more disordered in nature.

Thus, we can conclude that the second law of thermodynamics states that in any transformation, some of the original energy is converted to heat or light and the system becomes more disordered.
