THE AIR

We live at the bottom of an ocean of a gas that we call air. Air is the gas which we know best, and, in discussing gases (1), we shall use it as an example. You must remember, however, that the laws that apply to air apply to all other gases.

Air has weight. We can easily show it if we weigh an incandescent lamp. Heat a spot on the lamp red not (2), using a mouth blow-pipe (3). The air pres-sure will make a hole through the glass and the lamp will fill with air (4). weigh it again and you will find that the lamp weighs more than before, because it is now full of air. fill the lamp with water and find its volume. Now you have all the figures necessary to determine the weigh of one cubic foot of air. Thus we know that the weight of a cubic foot of air at (5) and 76 cm (6) pressure is.081 pound, or 12 cubic feet of air weigh a pound.

Since air has weight, it must press down on the surface of the earth. At sea level the pressure of the air on the surface of the earth is about 15 pounds per square inch. We often call this pressure of 15 Ib. per sq in (7) a pressure of one atmosphere, but the figure 15 is not exact because the pressure varies with the level of the place and the height of the barometer at the time.

The surface of the sea is level. What is the level of the liquid? Do you often read foreign press? Next year we shall buy two new presses. He pressed his friend's hot hand. Give me again the fifth volume of Jack London's works. Find the volume and the weight of this body. The volume of our work is now greater than it was before. Since we have all the figures, we must determine the weight of the ship. He was not here since last summer. I read the book through. You can see the sea bottom through the water.
