Thus the resulting pressure will be 4 P.
Explanation:
Gas law:
- VT = constant
- Initial temperature = T
- Initial Pressure = P
- Final temperature = 2 T
Solution:
Using ideal gas equation.
P1 V1 / T1 = P2 V2 / T2
P1 = P , T1 = T , V1 = V
According to VT = K
V2 / V1 = T1 / T2 = 1/2
V2 = V / 2
PV / T = P2 ( V / 2) / 2 T
P2 = 4 P
Thus the resulting pressure will be 4 P.
