Question
A fixed amount of ideal gas held at constant volume has its temperature increased from 400K to 500K. If it's initial gauge pressure at 400K is pg = 3.00 atm, what is its gauge pressure once it reaches 500K? A) 3.75 ATM B) 5.00 ATM C) 4.00 ATM D) 2.50 ATM A fixed amount of ideal gas held at constant volume has its temperature increased from 400K to 500K.

from isochoric law P1/P2=T1/T2
=> P2=(T2/T1)*P1
=> P2=( 500/400) * 3 atm
P2= 3.75 atm ans
