Abstract

This study aims to evaluate the effectiveness of Boyle's Law Apparatus in teaching the relationship between pressure and volume of gas at constant temperature, utilizing a structured cookbook practicum approach. An experimental method was employed at MA Alinayah Bandung, involving four variations of pressure and ten trials for each variation, resulting in a total of 40 trials. The tools used included vacuum tubes, vacuum pumps, manometers, and volume meters for accurate measurement of pressure and volume. Results demonstrated a consistent inverse relationship between gas volume and pressure, aligning with Boyle's Law, where P × V remained constant. The structured approach facilitated accurate data collection and enhanced students' comprehension of gas behavior principles. The findings highlight the importance of practical experimentation in physics education, providing students with hands-on experience and fostering critical thinking skills for a more interactive learning environment. Keywords: Boyle's Law; Gas Behavior; Experimental Method; Physics Education; Cookbook Practicum.

Abstract

This study aims to explain the molecular mechanisms controlling the surface tension of liquids and determine the magnitude of the surface tension of liquids. The research was conducted through laboratory experiments with variations in temperature and the addition of surfactants. Data was collected by dipping the device into soapy water and measuring the changes in string tension before and after immersion. The results showed that the surface tension of hot soapy water is lower than that of cold soapy water. This reduction in surface tension is due to the increased kinetic energy of molecules at higher temperatures. These findings are relevant in various scientific and industrial applications, including capillarity in plants, industrial cleaning, and understanding the hydrological cycle. This research provides a deeper understanding of surface tension and its implications in everyday life.
