Question

During an experiment an ideal gas is found to obey an additional gas law VT = Constant. The gas is initially at temperature T and pressure P. when it is heated to the temperature 2T. the resulting pressure

Answer 1

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.
