Constant pressure lines in the superheated region of the Mollier diagram will have

1. A positive slope
2. A negative slope
3. Zero slope
4. Both positive and negative slope

Correct Option: A

Mollier diagram is h-s diagram
Tds = dh – vdP
dP = 0
Tds = dh

	dh	= T
	ds

∵ T > 0

	dh	> 0
	ds

slope > 0
