The pressure of a gas at -173C temperature is 1 atmosphere, keeping the volume constant, to what temperature should the gas be heated so that its pressure becomes 2 atm?
At Initial state
pi = 1atm
T0=-173oc =100k
vi=v
Finally
Pf= 2 atm
Tf = ?
Vf= v(constant)
By ideal gas law
PV = nRT
V = T/P = constant
Ti/pi= Tf/pf
Tf = Ti*Pf/pi
=100*2/1
= 200k = -73oc
