Application
Study and demonstration of surface tension of liquids
Surface tension makes a liquid surface behave like a stretched elastic membrane, and this apparatus lets a class see and measure that effect. It suits physics and general science practicals on cohesion, adhesion, capillary action and the effect of impurities or temperature on a liquid surface. Educational Instrument can arrange export supply of the Instrument to study superficial tension to Libya, Oman, Senegal, Estonia and Eritrea.
Frequently Asked Questions
Is superficial tension the same as surface tension?
Yes. Superficial tension commonly refers to surface tension, the tension at a liquid surface caused by molecular attraction.
