(PLEASE HELP)
An ideal gas is allowed to expand from 4.20 L to 14.7 L at a constant temperature.
If the Initial pressure was 145 atm, what is the final pressure?

danjs · Answer

$$P*V=constant$$

$$P _{1}*V _{1}=P _{2}*V _{2}$$

$$P _{2} = \frac{ P _{1}*V _{1} }{ V _{2} }$$

Sorry but what even is P and does v= volume?

danjs · Answer

Pressure 1, P1 = 145 atm
Volume 1, V1 = 4.2 L

Pressure 2, P2 = Unknown
Volume 2, V2 = 14.7 L

T1 = T2 (isothermal process)
