Modern Chemistry
Chapter 1: The Language of Chemistry
Three very fundamental physical quantities are discussed: mass, weight, and volume. Mass and weight are not the same thing: while mass is the amount of matter, weight is a gravitational force. Volume is the region of space that an object may occupy. Duration: 10:17.
Kai shows Maile how the composition of a penny changed after 1982 and how the differences in mass can be detected by noting the differences in inertia. Duration 2:53.
Maile shows Kai the Decisive Dimensions Hands-On Chemistry activity, but to two end up in disagreement. Duration 2:27.
Density is a measure of how compact a material is. The greater the density, the more mass is squeezed into a particular volume. Mathematically, density is expressed as the ratio of mass to volume. Duration: 8:06.
