Surface Tension Explained: Formula, Apparatus Factors & Daily Life Examples-by Amjad Ali

Description: Understand surface tension in this complete chemistry lecture designed for FSc, NMDCAT, ECAT, and ETEA students. This video covers the definition of surface tension, its formula unit, the apparatus used to measure it in the laboratory, and the key factors that affect it, such as temperature, impurities, and intermolecular forces. You will also see clear daily life examples that show how surface tension works around us, from water droplets to insects walking on water. The explanation follows the FSc chemistry syllabus and is presented in a simple, exam-focused style suitable for board exams and entry test preparation. Watch till the end for a quick summary of important points that are often asked in tests and papers.
