need help with both questions please.
A gas is in a sealed container with a moveable piston. The original pressure is 109 kPa and the original volume is 0.210m'. If the piston is moved outward to make the volume 0.480 m2, what will the new pressure be? Assume that the temperature of the gas is kept constant. 47.7 kPa 0.00401 kPa 249 kPa 0.0210 kPa Now, suppose that the original conditions remain the same but the piston is moved inward...

A cylinder of monatomic ideal gas is sealed in a cylinder by a piston. Initially, the gas occupies a volume of 2.50 L and the pressure is initially 125 kPa. The cylinder is placed in an oven that maintains the temperature at a constant value. 80.0 J of work is then done on the piston, compressing the gas (in other words, the gas does -80 J of work). The work is done very slowly so that the gas maintains a...
