Equation of the gas state processes

Problem 2.2

Two identical vessels are connected by a tube with a valve letting the gas pass from one vessel into the other if the pressure difference Δp1.10\Delta p \geqslant 1.10 atm. Initially there was a vacuum in one vessel while the other contained ideal gas at a temperature t1=27Ct_{1}=27^{\circ} \mathrm{C} and pressure p1=1.00p_{1}=1.00 atm. Then both vessels were heated to a temperature t2=107C.t_{2}=107{ }^{\circ} \mathrm{C} . Up to what value will the pressure in the first vessel (which had vacuum initially) increase?

Reveal Answer
p=1/2(p1T2/T1Δp)=0.10 atm. p=1 / 2\left(p_{1} T_{2} / T_{1}-\Delta p\right)=0.10 \text { atm. }
