Question

If pressure of a gas is reduced by 25% then what should be the
temperature required to make its volume twice at stp?

Dear Student,

The computation are expressed below,

at STP,P1=1atm,  T1=273 Kat 25% reduction,P2=0
75 atm T2=?P1P2=T1T2⇒10 75=273T2⇒T2=204
75 KP1V1P2V2=T1T2⇒10 75×V1V2=27204 751
33×V1V2=1
33V1=V2Hence for doubling volume temperature have to be doubled at STP so we get,T=2×273=546 K
