Question

A process will not occur unless it satisfies the first law of thermodynamic or the second law of thermodynamics

O true
O false

Answer 1

It is false that a process can occur if it satisfies only one of the thermodynamic laws. Both the first law (conservation of energy) and the second law (entropy increase or constancy) must be satisfied for any process to be possible. Option B is correct.

Step-by-step explanation:

False. A process must satisfy both the first law of thermodynamics and the second law of thermodynamics to occur. The first law, also known as the law of conservation of energy, states that energy cannot be created or destroyed in an isolated system.

However, this is not the only condition for a process to occur. The second law introduces the concept of entropy and states that for any spontaneous process, the total entropy of a system either increases or remains constant; it never decreases.

This law explains why certain processes do not occur even if they do not violate the first law, such as heat spontaneously flowing from a colder to a warmer body.

Spontaneous processes, like heat flowing from hot to cold, must conform to this law of increasing entropy, and as such, many possible energy-conserving processes are not observed in nature because they would entail a decrease in entropy, which the second law forbids.
