Answer:

The final pressure is #=133.3 "torr"#

Explanation:

Apply Gay Lussac's Law

#" Pressure "/"Temperature (K)"=" Constant "#

When the volume is kept constant.

#P_1/T_1=P_2/T_2#

The initial pressure is #P_1=100 " torr"#

The initial temperature is #T_1=27^@C=273+27=300K#

The final temperature is #T_2=127^@C=273+127=400K#

The final pressure is

#P_2=T_2/T_1*P_1=400/300*100=133.3 "torr"#
