What is the purpose of using a glass tubing in the experiment on the determination of surface tension of a liquid by the capillary rise method? * No answer from the choices. The glass tubing serves as the tube O where air is blown into or suctioned out of with the help of an aspirator. The glass tubing serves as the tube where the liquid will rise and/or fall. The glass tubing serves as the tube where the thermometer is inserted for the measurement of the temperature of the liquid.
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
