Kinetic Theory of Gases · Gas laws and molecular picture
A gas of certain mass filled in a closed cylinder at a pressure of 3.23 kPa has temperature C. The gas is now heated to C. The modified pressure is Pa.
We corrected a printing error in the original paper
Source printed “heated to double its temperature”; reworded to “heated to C”, the reading behind the NTA key 3730 (doubling the absolute temperature would give 6460 Pa).
