The safety valve will melt when the gas pressure is approximately 40.7 ATM.
That is false. The safety valve will not melt when the gas pressure is approximately 40.7 mL.
The correct procedure for solving this problem is as follows:
Considering the ideal gas formula: PV = nRT,
Pressure and temperature have a direct relationship.
In other words, P = T
The formula, derived from the ideal gas formula to solve this problem is therefore:
P1 P2
___ = ____
T1 T2
P1 = 20.0 ATM
T1 = 20.3 degrees Celsius + 273.15 = 293.45 K
P2 = ?
T2 = 125 degrees Celsius + 273.15 = 398.15 K
P2 = ((20.0 ATM) (398.15 K))/(293.45 K)
P2= 27.13579826 ATM
P2 ~ 27.1 ATM (rounded using significant figures)
As can be seen, the pressure at which the metal alloy metals is 27.1 ATM.
