General Chemistry I CHEM-1411 Ch 1 Introduction Part 2

Section 1.4 The Nature of Energy: Some definitions of energy terms
Section 1.5 Units of Measurement: Getting familiar with SI Units, metric prefixes, temperature conversions. Doing density calculations.
Section 1.6 Uncertainty in Measurement (partial): Define precision and accuracy. Determine the number of significant figures in a written measurement and write the correct number of sig. figs. for one of your measurements.
These are the lectures that I use in my General Chemistry I course. The textbook I use is Brown, Theodore et al "Chemistry: The Central Science", Pearson, 14th Ed., 2018, ISBN13: 978-0134414232. Some images used in this video come from that textbook.
