Answer to Question #89009 in Physical Chemistry for yesenia L Luna

Question

If you have a flexible, closed container at room temperature in normal air (initial temperature = 298 K, constant pressure = 1 atm, constant n) and you see grow to 4 times its original volume, what must’ve happened?

Answer 1

PV=nRT

V = nRT/P

4V = 4nRT/P;

Consequently, if the volume increases 4 times, then the temperature will increase 4 times, or the

pressure will decrease 4 times.
