Which of the following statements is true about surface tension? * Surface tension is responsible for the ability of some solid objects like needles to "float" on the surface of a liquid. Surface tension measurements may be expressed in dynes or Poise. Surface tension of liquids can be measured by the capillary rise method using an Ostwald viscometer. Surface tension is a force directed perpendicular to the surface of the liquid and is acting towards the surface.

kindly help me with this simple question from which is the correct answer 

Which of the following statements is true about the experiment on the determination of surface tension of liquids by the capillary rise method? * In setting up the apparatus needed for the experiment, the glass tubing should be immersed in the liquid being investigated. The large test tube, capillary tube, and glass tubing should only be rinsed with hydrochloric acid as other liquids might contaminate all the apparatus. The capillary tube should be immersed in the liquid inside the test tube. The aspirator is used to blow and suction air into and out of the capillary tube.
