This is a variation of Charle's law

V/T = k k is a constant and T is degrees K (MUST BE IN DEGREES K)

FIRST -55 c + 273.15 = 218.15 K

30 c = 303.15 K

Now the original volume and temp 590 ml / 218.15 K = konstant = 2.70456

Now, assuming a constant pressure, the NEW volume

x ml / 303.15 =2.70456

x= 819.89 ml

Since they BOTH equal the k onstant , you can set it up as a ratio:

590/218.15 = x / 303.15 x = 819.89 ml
