00:01 The question says to find the correct statements out of the given statements here.

00:09 And what are the statements here? these are regarding the third law of thermodynamics.

00:14 So let's the explanation for it.

00:17 We will see each statement one by one.

00:20 So for statement one, what is given here? in a gaseous state, the entropy of system is zero.

00:30 So if we see in the gaseous state, the molecules have some randomness.

00:35 So we can say that their entropy will not be zero.

00:38 So this statement is a false statement.

00:45 Now what is a statement too here? it says at the melting point the entropy of a system increases abruptly as the compound transforms into a liquid.

00:55 So if we see that it is true at melting point the absolute entropy jumps suddenly as the phase changes from highly ordered solid to disordered liquid.

01:06 So we can say our second statement is a true statement.

01:12 If we see for the third statement, what is given here? at absolute zero, the interatomic distance within a crystal is minimized.

01:20 So if we see that the third statement is also true here, as at absolute zero temperature, the interatomic distance within a crystal is minimized.

01:31 It means the entropy here is minimized here.

01:35 So our third statement is also true.

01:39 If we see for the fourth statement, what is the fourth statement here? in a crystalline state, there is a tendency to minimize entropy...
