Answer:
Not Changed
Explanation:
To know what happened with the volume you need to know the Ideal gas Law
[tex]\frac{P_{1}V_{1}}{T1} =\frac{P_{2}V_{2} }{T2}[/tex]
This law is a combination of the other four laws: Boyles's, Charles's, Avogadro's, and Guy-Lussac's.
The initial state is represented by P1, V1, T1 and the final by P2, V2, T2.
In this case:
[tex]T_{2} =3T_{1} \\P_{2} =3P_{1}[/tex]
Replacing on the equation
[tex]\frac{P_{1}V_{1}}{T1} =\frac{3P_{1}V_{2}}{3T_{1} }[/tex]
If we clear from the equation V2
[tex]\frac{P_{1}V_{1}3T_{1}}{T_{1} 3P_{1}} ={V_{2}}[/tex]
Then cancel both P1 and T1
[tex]\frac{3V_{1}}{3} =V_{2}[/tex]
You will found that
[tex]V_{1} =V_{2}[/tex]
