The goal of the experiment This experiment aims to practically determine the density of a liquid. Experiment Tools Scale - Included tester - different liquids with different volumes Steps of the experiment Choose a few different sized liquids from the lab library. Weigh the tester blank inserted and......

This experiment aims to determine the density of solid objects by measuring their mass and volume. The mass is measured using a balance, while the volume is determined either from the object’s dimensions (if it has a regular shape) or by water displacement in a graduated cylinder (if irregular). The......
