I understand that the degree of freedom is the number of ways in which a molecule can acquire energy. I don't want you to explain the definition, but I want to see how it works. Please explain how is that a real thing, I want to see it. Try to describe the ways in which the molecule can acquire energy . I really can't see it.

Forget the energy. Degrees of freedom are the ways in which the molecule can stretch or bend. – Ivan Neretin Oct 13 '18 at 05:31

@IvanNeretin Whoa what is that sir. How can we tell the ways in which molecules bend. Why can't they bend however they want to. This is more confusing. – optimus prime Oct 13 '18 at 05:33

Why can't you bend your arm however you want to? – Ivan Neretin Oct 13 '18 at 06:10

1@IvanNeretin I don't study biology. But it maybe due to the bone joint design. Sir maybe I get this: Nature has its own designs – optimus prime Oct 13 '18 at 06:11

OK, forget the arm. Think of a diatomic molecule. In what way(s) can it stretch or bend? – Ivan Neretin Oct 13 '18 at 06:17
-
Both atoms can go upwards and go sideways and they can do it opposite directions . They can go at angles. They can bend around anywhere in the 360 degrees they got – optimus prime Oct 13 '18 at 06:21

Sure, but how many variables do you need to describe the way they are positioned relative to each other? – Ivan Neretin Oct 13 '18 at 18:31
-
@IvanNeretin 3 maybe? – optimus prime Oct 14 '18 at 02:58
-
Well, what are those 3? – Ivan Neretin Oct 14 '18 at 07:10
-
@IvanNeretin distance and angle between them ? – optimus prime Oct 14 '18 at 07:15
-
@IvanNeretin I first thought you asked about coordinates sir. Then I saw variables and the word "relative" – optimus prime Oct 14 '18 at 07:16
-
What's an angle between the two points? – Ivan Neretin Oct 14 '18 at 07:18
-
@IvanNeretin that not defined. But we can draw a horizontal passing through one point and specify the other's orientation with the angle . Right sir? – optimus prime Oct 14 '18 at 07:37
-
No. Imagine a molecule in which the two atoms are 2Å apart and one is above the other. Now imagine a similar molecule in which the two atoms are 2Å apart and both are in the same horizontal plane. Just how are they different? They aren't. – Ivan Neretin Oct 14 '18 at 07:51

@IvanNeretin Ok sir then I got it wrong . I'm listening – optimus prime Oct 14 '18 at 10:03

1See, there is only one variable: it is the distance between them. – Ivan Neretin Oct 14 '18 at 14:59

@IvanNeretin ok sir – optimus prime Oct 14 '18 at 15:05
