Easton Cherry · Answer 1

A. 0.5 L The idea gas law is PV = nRT where P = Pressure V = Volume n = amount of the substance R = Universal gas constant T = Absolute temperature. By doubling the pressure, you halve the volume. So if you started with 2.0 L, you now have 1.0 L. And by reducing the temperature from 400 K to 200 K, you halved the temperature. Which halves the volume. Therefore reducing the 1.0 L to 0.5 L.
