A tube 4.4 mm in diameter is run through the stopper of a sealed 8-liter container. The tube outside the container forms a U, then runs in a straight line with slope .015 with respect to horizontal. Alcohol is introduced into the tube, and fills the U, extending into the linear section of the tube. The end outside the container is sealed, and the air column in the linear section is originally .8 meters long.
The container is slightly heated, and the alcohol column is observed to move along the linear section of the tube. If the temperature of the air in the container was originally 23 Celsius, then if the temperature increases by .36 Celsius how far will the alcohol column move?
