A J-shaped tube, closed at one end, is depicted in the figure at the right. It contains N2 gas that is trapped by an unknown liquid whose density is twice as large as that of mercury. The other end of the tube is open to the air. The value of h is measured to be 10 mm at sea level on a clear day at a temperature of 27°C. The atmospheric pressure is 1.00 atm. Assuming the vapor pressure of the liquid is zero, what is the concentration of the N2 gas trapped inside the J-shaped tube?

How does the digestive system interact with the circulatory system? a. messages sent as electrical impulses from the digestive system are transported throughout the body by the circulatory system. b. nutrients taken in and broken down by the digestive system are carried to various parts of the body by the circulatory system. c. nutrients and gases are absorbed by organs in the circulatory system. then, they are transported to all parts of the body by organs in the digestive system. d. oxygen and carbon dioxide are exchanged by organs in the digestive system, and the gases are carried to the rest of the body by the circulatory system.
