A Sample of a Gas in a Cylindrical Chamber with a Movable

A sample of a gas in a cylindrical chamber with a movable piston occupied a volume of 1.40 liters when the pressure was 768 torr and the temperature was 26.9 °C. The volume of the system was readjusted to 2.16 liters by changing the temperature while the load on the piston was kept constant to keep the pressure in the system constant. What is the temperature in the system at this point?

A) 41.5 °C
B) 41.9 °C
C) 189.8 °C
D) 194.7 °C
E) 288.6 °C
