In this video Paul Andersen explains how chemical change differs from physical change. In the laboratory macroscopic observations are used to infer changes at the particulate level. Evidence for chemical change include gas production, change in temperature, change in odor, change in color, and formation of a precipitate.
In this lesson, we'll learn about the 2 most important tools to identify chemical hazards: , Safety Data Sheets (SDS) and , Chemical Labels Many of the chemicals we use in the lab are potentially dangerous, especially under high heat, pressure, or when they're mixed with other chemicals.
The video resource "The Chemical Mind - Crash Course Psychology #3" is included in the "Psychology" course from the resources series of "Crash Course". Crash Course is a educational video series from John and Hank Green.
