Question

Which statements about entropy are true?

1. Entropy is a measure of disorder in a system.

2. Entropy is a state function.

3. An increase in entropy is associated with an increase in the order of a system.

4.The minimal value of entropy is zero.

Answer 1

All the statements given above for entropy are correct and justifiable.

1. Entropy is a measure of disorder in a system.

TRUE, it tells us about randomness in a system

2. Entropy is a state function.

TRUE, entropy doesnt depends on the path followed for process instead only depends on the initial and final states of system.

3. An increase in entropy is associated with an increase in the order of a system.

FALSE, it is associated with disorder or chaos in the system so when the entropy increases the disorderness of system increases

4.The minimal value of entropy is zero

TRUE, the value of entropy at absolute zero temperature(-273.15 ⁰c) is accounted to be zero and is minimal value.
