The video tutorial demonstrates an experiment to identify the gas in a lighter using a graduated cylinder, water, and a scale. The process involves weighing the lighter, filling a cylinder with water, capturing the gas, and using the ideal gas law to calculate the moles of gas. The experiment concludes by identifying the gas as butane based on its weight and demonstrating its properties.
