When water fills a narrow glass tube, the top surface of the water turns out not to be flat. First, (i) describe what the surface of water in a glass tube looks like (you may draw a picture instead of or in addition to your written answer). Next, (ii) state the term used to describe this phenomenon. Then, briefly (iii) explain why the surface of the water changes in this way. Finally, (iv) explain how the volume of water in such a tube is properly determined given what happens to the water’s surface.    *THIS IS THE QUESTION BUT I ONLY NEED STEP 3 AND STEP 4.
