If you mean pattern designs it’s rocky bumpy and you can see the circle patterns
If you mean phases the here’s a picture
We can obtain the answer easily if we assume the gas here is an ideal gas. We can use t he expression:
PV = nRT
we set nR/V = k
P/T = k
P1/T1 = P2/T2
when P2 = 3P1
P1/10 = 3P1/T2
T2 = 30 degrees Celsius
