I will use (p2v2/t2)=(p1V1/t1)

(pressure one) p1 = 200kPa

(pressure two) p2 = ?

(volume one) v1 = 1 (because its a constant)

(volume two) v2 = 1 (again, constant)

(temperature one) t1 = 20C = 293 K

(temperature two) t2 = 50K = 323 K

I solve for p2, but i get 220, not 230 as the book says. It might have something to due with the comment in the question about gauge pressure. Anyone see the problem?
