Experiment 2 Lab Techniques and Measurements

Procedure: Using distilled water, premeasured containers and objects determine displacement of fluids and density of objects. Use ice and heat measure temperatures in Celsius, Fahrenheit and Kelvin.

Purpose: Weighing objects. Figuring out the density with an object by calculated volume and Archimedes’ Principle.
