The new volume is #=26L#

Apply Charles' Law

#"volume"/"Temperature"="Constant"#, #"At constant pressure"#

#V_1/T_1=V_2/T_2#

The initial volume is #=V_1=18L#

The initial temperature is #T_1=170+273=443K#

The final temperature is #T_2=640K#

The final volume is

#V_2=T_2/T_1*v_1=640/443*18=26L#
