A sealed container containing 5.0 mol of gas is squeezed, changing its volume from 2.5×10-2 m3 to 1.5×10-2 m3. During this process, the temperature decreases by 8.0 K while the pressure increases by 300 Pa.
What was the original pressure of the gas in the container?
What was the original temperature of the gas in the container?
