Hey there !!!!!
PV=nRT
at constant pressure
Volume is directly proportional to temperature .
Initial Volume = 500 Temperature =273K
Final Volume = 260 Final temperature = t K
initial volume/final volume = initial temp/final temp
500/260 =273/t
t=273*260/500
t=141.96 K
Hope this helped you ....................................
