If perfect gas heat up to vol. is double of initial vol. at constant pressure , the initial T1 is 30c so T2?

Question

If perfect gas heat up to vol. is double of initial vol. at constant pressure , the initial T1 is 30c so T2?

Answer 1

increase in volume is directrly proportional to increase in temp at constant pressure.... its Charles Law..

But temp should be in kelvin

30 Celcius = 303 K

Hence final temp will be twice of 303 K i.e 606 K or 333 celcius

Answer 2

acoording to Ideal gas equation, At constant presssure,

V1.T2 = V2.T1

But here, temperature must be put in Kelvin.

Put V1=V,

       V2=2V,

       T1=30+273=303K,

       T2=?

and now I think u can put the values & get the answer........
