A rigid container of O2 has a pressure of 340 kPa at a temperature of 713 K. What is the pressure at 273 K? Show your work.
Please help me with this question. I don’t know how to answer it. Thanks. Show me the work you did and then explain how you did it if possible.

Apply the Ideal Gas Law :
———————————————————–
[P1 ] [ V1 ] / [ T1 ] = [ P2 ] [ V2 ] / [ T2 ]
[ P2 ] = [ P1 ] [ V1 / V2 ] [ T2 / T1 ]
[ P2 ] = [ 340 ] [ 1.000 ] [ 273.0 / 713.0 ] = 130 kPa. <—————————
I hope this is helpful to you.
