remains constant. A pure substance melts at a precisely defined temperature‚ characteristic of every crystalline substance and dependent only on pressure (though the pressure dependency is generally considered insignificant). Determining the MP is a simple and fast method used in many diverse areas of chemistry to obtain a first impression of the purity of a substance. This is because even small quantities of impurities change the melting point‚ or at least clearly enlarge its melting range. The boiling

Goals The purpose of the lab experiment is to explore simple harmonic motion (SHM). We will accomplish this through the validation of harmonic calculations and ultimately creating a time piece (oscillator) Method In part A (Simple Pendulum) we will measure the effects of mass on the period of the pendulum. We will also calculate the period using small angular displacements and compare the results. We will also explore the effects on the period when the angular displacement is not “very small”
