#P_f=3.43" "Pa#

#P_i:"initial pressure (Pa)"#
#P_f:"final pressure (Pa)"#
#T_i:"initial temperature (Kelvin)"#
#T_f:"final temperature (Kelvin)"#

#"given data:"#
#P_i=4Pa#
#P_f=?#
#T_i=220+273=493 " "^o K#
#T_f=150+273=423" "^o K#

#"We can use the Gay-Lussac's Law to calculate the problem"#

#P_i/T_i=P_f/T_f#

#4/493=P_f/423#

#P_f=(4*423)/493#

#P_f=3.43" "Pa#
