The final pressure is $=133.3 "torr"$

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

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

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