You can put this solution on YOUR website!
PV+=+nRT
You are told that P and n don't change. R is a constant. So the relationship between Volume and Temperature is direct.
You can then write this as
V%2FT+=+nR%2FP
Since everything on the right side is held contstant, you can then say
V%5B1%5D%2FT%5B1%5D+=+V%5B2%5D%2FT%5B2%5D
Now just plug in the givens and solve
20%2F273+=+30%2FT%5B2%5D
T%5B2%5D+=+30%2A273%2F20
T%5B2%5D+=+409.5 Kelvin
