the entire statement is true and correct.  

there's no diagram, nothing is illustrated, and no question is asked.

overcharge is the right answer system

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?
