Question

Certain amount of gas occupy a volume of 400ml at 17°c . To what temperature should it be heated so that the volume is reduced to half. PLZZ ANSWER THIS QUESTIOM

Answer 1

Hey there !!!

PV=nRT 

at constant pressure 

Volume is directly proportional to temperature .

Initial Volume = 400  Temperature =17°C= 273+17=300K

Final Volume = 200   Final temperature = t K

initial volume/final volume = initial temp/final temp 

400/200 =300/t

2=300/t

t= 150 K

So 150 K is temp at which volume becomes half.

Hope this helped you ....
