A 1.00 mol sample of an ideal gas is confined in a cylinder fitted with a movable piston at an initial state of 1.00 atm and 300 K. The gas is compressed to one-half of its original volume while simultaneously being heated to 600 K. What is the final pressure of the gas?
a) 2.00atm
b) 8.00atm
c) 4.00atm
d) 0.50atm
