T1 = 60oC = 333oK
T2 = 180oC= 180 + 273 = 453
V1 = 200 cm^3
V2 = ??
200/333 = V2 / 453
V2 = 200 * 453/333
V2 = 272 cm^3

The general idea here is the PV = k
P = k/V
The relationship is indirect. As V increases P decreases. You are dividing a bigger number into a constant.
Answer: inverse <<<=======
Three
=====
PV = nRT
You have to establish that the units for R are the same as the givens. If not the givens have to be converted to something else. From the question, I'm not sure they are the same, but I can't tell what is intended. So I'll assume everything is fine.
n = PV/RT
n = 1000 kPa * 12.0 L / (8.31 * 298o K)
n = 4.85 mols

it should be one. Let's make sure.
V = 22.4 L
T = 273oK
R = 8.31
P = 101.3 kPa Google STP pressure in kPa
n = PV/R*T
n = 101.3 * 22.4 / (273 * 8.31)
n = 1.0002 which is close enough to 1

You should be able to get this on your own. Look at question 1 above.
I've done a lot her. I need 5 Brainlys to move up. Could you award one please?
