What is the value of 1.5 ATM of gas at 20°C and a 3 L vessel are heated at 30°C at a pressure of 5.2 ATM
vampirchik [111]

Answer:

The answer will be approximately 1.0L

Explanation:

The problem has not been properly specified. You could have specified a gas in a PISTON, whose volume would decrease with increased pressure, and increase with increased temperature.

For such a system, we would use the  

combined gas law:

\frac{P1V1}{T1}=\frac{P2V2}{T2}

V_{2}= \frac{P1V1}{T1}\times\frac{T2}{P2}

                       =\frac{1.5\times3.0\times303}{293\times5.2}

                        \approx1.0L
