At 25°C, gas in a rigid cylinder with a movable piston has a volume of 145 mL and a pressure of 125 kPa. Then the gas is compressed to a volume of 80. mL. What is the new pressure of the gas if the temperature is held at 25°C?(1) 69 kPa (3) 160 kPa
(2) 93 kPa (4) 230 kPa

p1v1=p2v2
=> p1v1
     ---------
      v2
=> 125x145
      -----------
        80
=> p2=226.56kPa
This answer is expected as well, the volume decreases so the pressure will increase.
